Agere Systems Inc. 15
* Differential pairs are indicated by P and N suffixes. For nondifferential signals, N at the end of the symbol name designates active-low.
† I = input, O = output. IU indicates an internal 50 kΩ pull-up resistor on this ball. ID indicates an internal 50 kΩ pull-down resistor on this ball.
* For information on power supply filtering and grouping, see the TSWC01622 Power Supply Grouping and Filtering Application Note.
Table 4-8. Test and Reserved Signals
Ball Symbol*Type†Level Name/Description
B15 TSTMODE IDCMOS Test Mode. Internal test observation signal used in test mode. Do not connect or
apply any signal to this ball.
B16
C16
TSTCLKP
TSTCLKN
IDLVDS Test Clock Input. Do not connect or apply any signal to these balls.
P11 MON8K OCMOS Monitor 8 kHz from Input Clock. Internal test observation signal. Do not connect
or apply any signal to this ball. (If the input clock is setup and applied correctly, this
signal should measure exactly 8 kHz.)
M4 SDH_HW IDCMOS Internal Signal. Internal test signal. Do not connect or apply any signal to this ball.
(When set to a CMOS logic high, the SDH block takes information directly from the
external leads and does not use information from the internal bus (registers).)
