General Description
The CrimzonTM ZLR16300 is a ROM-based member of the MCU family of general
purpose microcontrollers. With 236B of general-purpose RAM and 4KB to 16KB of
program memory, ZiLOG®’s CMOS microcontrollers offer fast-executing, efficient
use of memory, sophisticated interrupt s, input/out put bit manipulation cap ab ilities,
automated pulse generation/reception, and internal key-scan pull-up transistors.
The ZLR16300 architecture (Figure 1) is based on ZiLOG®’s 8-bit microcontroller
core with an Exp anded Register File allowing access to register-mapped peripher-
als, input/output (I/O) circuits, and powerful counter/timer circuitry. The Z8® core
offers a flexible I/O scheme, an efficient register and address space structure, and
a number of ancillary features that are useful in many consumer, automotive,
computer peripheral, and battery-operated hand-held applications.
There are three basic address spaces available to support a wide ran ge of config-
urations: Program Memory, Register File and Expanded Register File. The regis-
ter file is composed of 256B of RAM. It includes three I/O port registers, 16 control
and status registers, and 236 general-purpose registers. The Expanded Register
File consists of two additional register groups (F and D).
To unburden the program from coping with such real-time problems as generating
complex waveforms or receiving and demodulating complex waveform/pulses, the
CrimzonTM ZLR16300 offers a new inte lligent count er/timer architecture with 8-bit
and 16-bit counter/timers (see Figure 2). Also included are a large number of
user-selectable modes and two on-board comparators to process analog signals
with separate reference voltages.
All signals with an overline, “ ”, are active Low. For example,
B/W, in which WORD is active Low, and B/W, in which BYTE is
active Low.
Power connections use the conventional descriptions listed in Table 2.

Pin Functions
XTAL1 Crystal 1 (Time-Based Input)
This pin connects a parallel-resonant crystal, ceramic resonator, or LC to the on-
chip oscillator input. Additionally, an external single -phase clock can be connected
to the on-chip oscillator input.
XTAL2 Crystal 2 (Time-Based Output)
This pin connects a parallel-resonant, crystal, ceramic resonant, or LC to the on-
chip oscillator output.
Port 0 (P07–P00)
Port 0 is an 8-bit, bidirectional, CMOS-compatible port. These eight I/O lines are
configured under software control as a nibble I/O port. The output drivers are
push-pull or open-drain controlled by bit D2 in the PCON register.
If one or both nibbles are needed for I/O operation, they must be configured by
writing to the Port 0 mode register. After a hardware reset, Port 0 is configured
(Figure 7) as an input port.
An optional pull-up transistor is available as a OTP/mask option on all Port 0 bits
with nibble select.
Internal pull-ups are disabled on any given pin or group of port
pins when programmed into Output mode.
The Port 0 direction is reset to its default state following an
SMR.

Figure 7. Port 0 Configuration
Port 2 (P27–P20)
Port 2 is an 8-bit, bidirectional, CMOS-compatible I/O port (see Figure 8). These
eight I/O lines can be independently configured under software control as inputs
or outputs. Port 2 is always available for I/O operation. A mask optio n is available
to connect eight pull-up transistors on this port. Bits programmed as outputs are
globally programmed as either push-pull or open-drain. The POR resets with the
eight bits of Port 2 configured as inputs.
Port 2 also has an 8-bit input OR and AND gate, which can be used to wake up
the part. P20 can be programmed to access the edge-detection circuitry in
Demodulation mode.

Comparator Inputs
In analog mode, P31 and P32 have a comp arator front end. The comp arator refer-
ence is supplied to P33 and Pref1. In this mo de, the P33 internal data latch and it s
corresponding IRQ1 are diverted to the SMR sources (excluding P31, P32, and
P33) as indicated in Figure 9 on page 15. In digital mode, P33 is used as D3 of
the Port 3 input register, which then generates IRQ1.
Comparators are powered down by entering Stop Mode. For
P31–P33 to be used in a Stop Mode Recovery source, these
inputs must be placed into Digital mode.
Comparator Outputs
These channels can be programmed to be output on P34 and P37 through the
PCON register.
Functional Description
These devices incorporate special functions to enhance the Z8®’s funct ionality in
consumer and battery-operated applications.

The upper nibble of the register pointer (see Figure 13) selects which working reg-
ister group, of 16 bytes in the register file, is accessed out of the possible 256. The
lower nibble selects the expanded register file bank and banks 0, F, and D are
implemented. A 0h in the lower nibble allows the normal register file (bank 0) to be
addressed. Any other value from 1h to Fh exchanges the lower 16 registe rs to the
selected expanded register bank.

Register File
The register file (ban k 0) consists of 3 I/O po rt regist ers, 237 general-p urpose reg-
isters, 14 control and status registers (R0, R2, R3, R4–R239, and R240–R255,
respectively), and two expanded register Banks D (see Table 10) and F. Instruc-
tions can access registers directly or indirectly through an 8-bit address field,
thereby allowing a short, 4-bit register address to use the Register Pointer
(Figure 14). In the 4-bit mode, the register file is divided into 16 working register
groups, e ach occupying 16 cont inuous loca tions. The Registe r Pointer ad dresses
the starting location of the active working register group.
Register address E0h–EFh can only be accessed through
working registers and indirect addressing modes.

T8 Enable
This field enables T8 when set (written) to 1.
Single/Modulo-N
When set to 0 (Modulo-N), the counter reloads the initial value when the terminal
count is reached. When set to 1 (Single-Pass), the counter stops when the termi-
nal count is reached.
Timeout
This bit is set when T 8 times out (terminal co unt reached). To reset this bit, write a
1 to its location.
Writing a 1 is the only way to reset the Terminal Count
status condition. Reset this bit before using/enabling the
counter/timers.
The first clock of T8 might not have complete clock width
and can occur any time when enabled.
Take care when using the OR or AND commands to manipulate
CTR0, bit 5 and CTR1, bits 0 and 1 (Demodulation Mode).
These instructions use a Read-Modify-W rite sequence in which
the current status from the CTR0 and CTR1 registers is ORed
or ANDed with the designated value and then writ ten back into
the registers.
Example
When the status of bit 5 is 1, a timer reset condition occurs.

T8/T16_Logic/Edge_Detect
In Transmit Mode, this field defines how the outputs of T8 and T16 are combined
(AND, OR, NOR, NAND).
In Demodulation Mode, this field defines which edge should be detected by the
edge detector.
Transmit_Submode/Glitch Filter
In Transmit Mode, this field defines whether T8 and T16 are in the Ping-Pong
mode or in independent normal operation mode. Setting this field to “Normal
Operation Mode” terminates the “Ping-Pong Mode” operation. When set to 10,
T16 is immediately forced to a 0; a setting of 11 forces T16 to output a 1.
In Demodulation Mode, this field defines the width of the glitch that must be fil-
tered out.
Initial_T8_Out/Rising_Edge
In Transmit Mode, if 0, the output of T8 is set to 0 when it starts to count. If 1, the
output of T8 is set to 1 when it starts to count. When the counter is not enabled
and this bit is set to 1 or 0, T8_OUT is set to the opposite state of this bit. This
ensures that when the clock is enabled, a transition occurs to the initial state set
by CTR1, D1.
In Demodulation Mode, this bit is set to 1 when a rising edge is detected in the
input signal. In order to reset the mode, a 1 should be written to this location.
Initial_T16 Out/Falling _Edge
In Transmit Mode, if it is 0, the output of T16 is set to 0 when it start s to count. If it
is 1, the output of T16 is set to 1 when it starts to count. This bit is ef fective only in
Normal or Ping-Pong Mode (CTR1, D3; D2). Wh en the counter is not enable d and
this bit is set, T16_OUT is set to the opposite state of this bit. This ensures that
when the clock is enabled, a transition occurs to the initial state set by CTR1, D0.
In Demodulation Mode, this bit is set to 1 when a falling edge is detected in the
input signal. In order to reset it, a 1 should be written to this location.
Modifying CTR1 (D1 or D0) while the counters are enabled
causes unpredictable output from T8/16_OUT.

Input Circuit
The edge detector monitors the input signal on P31 or P20. Based on CTR1 D5–
D4, a pulse is generated at the Pos Edge or Neg Edge line when an edge is
detected. Glitches in the input signal that have a width less than specified (CTR1
D3, D2) are filtered out (see Figure 15).

When T8 is enabled, the output T8_OUT switches to the initial value (CTR1, D1).
If the initial value (CTR1, D1) is 0, TC8L is loaded; otherwise, TC8H is loaded into
the counter. In Single-Pass Mode (CTR0, D6), T8 counts down to 0 and stops,
T8_OUT toggles, the timeout status bit (CTR0, D5) is set, and a timeout interrupt
can be generated if it is enabled (CTR0, D1). In Modulo-N Mode, upon reaching
terminal count, T8_OUT is toggled, but n o in terrupt is gene rated. From that point,
T8 loads a new count (if the T8_OUT level now is 0), TC8L is loaded; if it is 1,
TC8H is loaded. T8 counts down to 0, toggles T8_OUT, and sets the timeout sta-
tus bit (CTR0, D5), thereby generating an interrupt if enabled (CTR0, D1). One
cycle is complete. T8 then loads from TC8H or TC8L according to the T8_OUT
level and repeats the cycle. See Figure 17.
Figure 17. 8-Bit Counter/Timer Circuits
The values in TC8H or TC8L can be modified at any time. The new values take
effect when they are loaded.
To ensure known operation do not write these registers at
the time the values are to be loaded into the counter/timer.
An initial count of 1 is not allowed (a non-function occurs).
An initial count of 0 causes TC8 to count from 0 to FFh to
FEh.

The letter h denotes hexadecimal values.
Transition from 0 to FFh is not a timeout condition.
Using the same instructions for stopping th e counter/timers
and setting the status bits is not recommended.
Two successive commands are necessary. First, the counter/timers must be
stopped. Second, the status bits must be reset. These commands are required
because it takes one counter/timer clock interval for the initiated event to actually
occur. See Figure 18 and Figure 19.

The user must program TC8L and TC8H to FFh. After T8 is enabled, whe n the first
edge (rising, falling, or both depending on CTR1, D5; D4) is detected, it starts to
count down. When a subsequent edge (rising, falling, or both depending on
CTR1, D5; D4) is detected during counting, the current value of T8 is comple-
mented and put into one of the capture registers. If it is a positive edge, dat a is put
into LO8; if it is a negative edge, data is put into HI8. From that point, one of the

T16 Transmit Mode
In Normal or Ping-Pong mode, the output of T16 when not enabled, is dependent
on CTR1, D0. If it is a 0, T1 6_OUT is a 1; if it is a 1, T16_OUT is 0 . You can force
the output of T16 to either a 0 or 1 whether it is enabled or not by programming
CTR1 D3; D2 to a 10 or 11 .
When T16 is enabled, TC16H * 256 + TC16L is loaded , and T16_OUT is switched
to its initial value (CTR1, D0). When T16 counts down to 0, T16_OUT is toggled
(in NORMAL or PING-PONG mode), an interrupt (CTR2, D1) is generated (if
enabled), and a status bit (CTR2, D5) is set. See Figure 22.
Figure 22. 16-Bit Counter/Timer Circuits
Global interrupts override this function as described in
“Interrupts” on page 43.
If T16 is in Single-Pass mode, it is stopped at this point (see Figure 23). If it is in
Modulo-N Mode, it is loaded with TC16H * 256 + TC16L, and the counting contin-
ues (see Figure 24).
The values in TC16H and TC16L can be modified at any time. The new values
take effect when they are loaded.

Do not load these registers at the time the values are to be
loaded into the counter/timer to ensure known operation.
An initial count of 1 is not allowed. An initial count of 0
causes T16 to count from 0 to FFFFh to FFFEh. Transition
from 0 to FFFFh is not a timeout condition.
Figure 23. T16_OUT in Single-Pass Mode
Figure 24. T16_OUT in Modulo-N Mode
T16 Demodulation Mode
The user must program TC16L and TC16H to FFh. After T16 is enabled, and the
first edge (rising, falling, or both depending on CTR1 D5; D4) is detected, T16
captures HI16 and LO16, reloads, and begins counting.
If D6 of CTR2 Is 0
When a subsequent edge (rising, falling, or both depending on CTR1, D5; D4) is
detected during counting, the current count in T16 is complemented and put into
HI16 and LO16. When dat a is captured, one of the edge dete ct status bit s (CTR1,
D1; D0) is set, and an interrupt is g enerated if enab led (CT R2, D2). T16 is loaded
with FFFFh and starts again.
This T16 mode is generally used to measure space time, the length of time
between bursts of carrier signal (marks).

If D6 of CTR2 Is 1
T16 ignores the subsequent edges in the input signal and continues counting
down. A timeout of T8 causes T16 to capture its current value and generate an
interrupt if enabled (CTR2, D2). In this case, T16 does not reload and continues
counting. If the D6 bit of CTR2 is toggled (by writing a 0 then a 1 to it), T16 cap-
tures and reloads on the next edge (rising, falling, or both depending on CTR1,
D5; D4), continuing to ignore subsequent edges.
This T16 mode generally measures mark time, the length of an active carrier sig-
nal burst.
If T16 reaches 0, T16 continues counting from FFFFh. Meanwhile, a status bit
(CTR2 D5) is set, and an interrupt timeout can be generated if enabled (CTR2
D1).
Ping-Pong Mode
This operation mode is only valid in Transmit Mode. T8 and T16 must be pro-
grammed in Single-Pass mode (CTR0, D6; CTR2, D6), and Ping-Pong mode
must be programmed in CTR1, D3; D2. The user can begin the operation by
enabling either T8 or T16 (CTR0, D7 or CTR2, D7). For example , if T8 is enabled,
T8_OUT is set to this initial value (CTR1, D1). According to T8_OUT's level,
TC8H or TC8L is loaded into T8. After the terminal count is reached, T8 is dis-
abled, and T16 is enabled. T16_OUT then switches to it s initia l value (CTR1, D0),
data from TC16H and T C16L is loaded, and T16 st arts to count. After T16 reache s
the terminal count, it stops, T8 is enabled again, repeating the entire cycle. Inter-
rupts can be allowed when T8 or T16 reaches terminal control (CTR0, D1; CTR2,
D1). To stop the ping-pong operation, write 00 to bits D3 and D2 of CTR1. See
Figure 25.
Enabling ping-pong operation while the counter/timers are
running might cause intermittent counter/timer function. Disable
the counter/timers and reset the status flags before instituting
this operation.

Initiating Ping-Pong Mode
First, make sure both counter/timers are not running. Set T8 into Single-Pass
mode (CTR0, D6), set T16 into Single-Pass mode (CTR2, D6), and set the Ping-
Pong mode (CTR1, D2; D3). These instructions can be in random order. Finally,
start Ping-Pong mode by enabling either T8 (CTR0, D7) or T16 (CTR2, D7). See
Figure 26.

The initial value of T8 or T16 must not be 1. If you stop the timer and restart the
timer, reload the initial value to avoid an unknown previous value.

During Ping-Pong Mode
The enable bits of T8 and T16 (CTR0, D7; CTR2, D7) are set and cleared alter-
nately by hardware. The timeout bits (CTR0, D5; CTR2, D5) are set every time the
counter/timers reach the terminal count.
Interrupts
The ZLR16300 features six different interrupts (Table 14). The interrupts are
maskable and prioritized (Figure 27). The six sources are divided a s follows: three
sources are claimed by Port 3 lines P33–P31, two by the counter/timers
(Table 14) and one for low voltage detection. The Interrupt Mask Register (globally
or individually) enables or disables the six interrupt requests.
The source for IRQ is determined by bit 1 of the Port 3 mode register (P3M).
When in digital mode, Pin P33 is the source. When in Analog mode the output of
the Stop Mode Recovery source logic is used as the source for the interrupt. See
Figure 32, Stop Mode Recovery Source, on page 52.

When more than one interrupt is pen ding, prio ritie s a re resolved b y a prog ramma-
ble priority encoder controlled by the Interrupt Priority Register. An interrupt
machine cycle activates when an interrupt request is granted. As a result, all sub-
sequent interrupts are disabled, and the Program Counter and Status Flags are
saved. The cycle then branches to the program memory vector location reserved
for that interrupt. All interrupts are vectored through locations in the program
memory. This memory location and the next byte cont ain the 16-bit ad dress of the
interrupt service routine for that particular interrupt request. To accommodate
polled interrupt systems, interrupt inputs are masked, and the Interrupt Request
register is polled to determine which of the interrupt requests require service.
An interrupt resulting from AN1 is mapped into IRQ2, and an interrupt from AN2 is
mapped into IRQ0. Interrupts IRQ2 and IRQ0 can be rising, falling, or both edge
triggered. These interrupts are programmable by the user. The software can poll
to identify the state of the pin.
Programming bits for the Interrupt Edge Select are located in the IRQ Register
(R250), bits D7 and D6. The configuration is indicated in Table 15.

Clock
The device’s on-chip oscillator has a high-gain, parallel-resonant amplifier, for
connection to a crystal, LC, ceramic resonator, or any suitable external clock
source (XTAL1 = Input, XTAL2 = Output). The crystal must be AT cut, 1 MHz to 8
MHz maximum, with a series resista nce (RS) less than o r equal to 100 Ω. The on-
chip oscillator can be driven with a suitable external clock source.
For 32-kHz crystal operation, an external feedback (Rf) and a serial resistor (Rd)
are required. See Figure 28.
The crystal must be connected across XTAL1 and XTAL2 using the recommended
capacitors (cap acitance greater than or equal to 22 pF) from each pin to ground.

Power-On Reset
A timer circuit clocked by a dedicated on-board RC-oscillator is used for the
Power-On Reset (POR) timer function. The POR time allows VDD and the oscilla-
tor circuit to stabilize before instruction execution begins.
The POR timer circuit is a one-shot timer triggered by one of three conditions:
•
Power Fail to Power OK status, including Waking up from VBO Standby
•
Stop-Mode Recovery (if D5 of SMR = 1)
•
WDT Timeout
The POR timer is 1 ms minimum. Bit 5 of the Stop-Mode Register determines
whether the POR timer is bypassed af ter S top-Mode Recovery (typical for external
clock, RC and LC oscillators).
Halt Mode
This instruction turns off the internal CPU clock, but not the XTAL oscillation. The
counter/timers and external interrupts IRQ0, IRQ1, IRQ2, IRQ3, IRQ4, and IRQ5
remain active. The devices are recovered by interrupts, either externally or inter-
nally generated. An interrupt request must be executed (enabled) to exit Halt
Mode. After the interrupt service routine, the program continues from the instruc-
tion after the Halt.
Stop Mode
This instruction turns off the internal clock and external crystal oscillation, reduc-
ing the standby current to 10 µA or less. Stop Mode is terminated only by a reset,
such as WDT timeout, POR or SMR. This condition causes the processor to
restart the application program at address 000Ch. In order to enter Stop (or Halt)
mode, first flush the instruction pipeline to avoid suspending execution in mid-
instruction. Execute an NOP instruction (Opcode = FFh) immediately before the
appropriate sleep instruction, as follows:

Stop-Mode Recovery Register (SMR)
This register selects the clock divide value and determines the mode of Stop
Mode Recovery (Figure 30). All bits are write only except bit 7, which is read only.
Bit 7 is a flag bit that is hardware set on the condition of Stop recovery and reset
by a power-on cycle. Bit 6 controls whether a low level or a high level at the XOR-
gate input (Figure 32 on page 52) is required from the recovery source. Bit 5 con-
trols the reset delay after recovery. Bits D2, D3, and D4 of the SMR register spec-
ify the source of the Stop-Mode Recovery signal. Bits D0 determines if SCLK/
TCLK are divided by 16 or not. The SMR is located in Bank F of the Expanded
Register File at address 0Bh.

Watch-Dog Timer Mode Register (WDTMR)
The W atch -Dog Timer (WDT) is a retriggerable one-shot timer that reset s the Z8®
if it reaches it s terminal count. The WDT must initially be enabled by executing the
WDT instruction. On subsequent executions of the WDT instruction, the WDT is
refreshed. The WDT circuit is driven by an on-board RC-oscillator. The WDT
instruction affects the Zero (Z), Sign (S), and Overflow (V) flags.
The POR clock source the internal RC-o scillator. Bits 0 and 1 of the WDT reg ister
control a tap circuit tha t determines the minimum timeout period. Bit 2 determines
whether the WDT is active during HALT, and Bit 3 determines WDT activity during
STOP. Bits 4 through 7 are reserved (Figure 34). This register is accessible only
during the first 60 processor cycles (120 XTAL clocks) from the execution of the
first instruction after Power-On-Reset, Watch-Dog Reset, or a Stop-Mode
Recovery (Figure 33). After this point, the register cannot be modified by any
means (intentional or otherwise). The WDTMR cannot be read. The register is
located in Bank F of the Expanded Register File at address location 0Fh. It is
organized as illustrated in Figure 34.

WDTMR During Stop (D3)
This bit determines whether or not the WDT is active during Stop Mode. Because
the XTAL clock is stopped during Stop Mode, the on-board RC has to be sele cted

The default is 1.
ROM Selectable Options
There are five ROM Selectable Options to choose from based on ROM code
requirements. These options are listed in Table 19.
Voltage Brown-Out/Standby
An on-chip Voltage Comparator checks that the VDD is at the required level for
correct operation of the device. Reset is globally driven when VDD falls below VBO.
A small drop in VDD causes the XTAL1 and XTAL2 circuitry to stop the crystal or
resonator clock. If the VDD is allowed to st ay above VRAM, the RAM content is pre-
served. When the power level is returned to above VBO, the device performs a
POR and fu nctions normally.

Low-Voltage Detection Register—LVD(0D)0Ch
Voltage detection does not work at Stop mode. It must be
disabled during Stop mode in order to reduce current.
Do not modify register P01M while checking a low-voltage
condition. Switching noise of both ports 0 and 1 together might
trigger the LVD flag.
Voltage Detection and Flags
The Voltage Detection register (LVD, register 0Ch at the expanded register bank
0Dh) offers an option of monitoring the VCC voltage. The Voltage Detection is
enabled when bit 0 of LVD register is set. When Voltage Detection is enabled, the
the VCC level is monitored in real time. The flags in the LVD register valid 20uS
after Voltage Detection is enabled. The HVD flag (bit 2 of the LVD register) is set
only if VCC is lower than the VHVD. When Voltage Detection is enabled, the LVD
flag also triggers IRQ5. The IRQ bit 5 latches the low voltage condition until it is
cleared by instructions or reset. The IRQ5 int errupt is served if it is enabled in the
IMR register. Otherwise, bit 5 of IRQ register is latched as a flag only.
Voltage Detection cannot be emulated with the emulator.
