To start communications, the master sets SDA to L while SCL set to H (Start condition). To finish communications, the master sets SDA to H while SCL set to H (Stop condition). During transfer, the 2 master changes SDA only while SCL is L. Figure 25. shows Start condition and Stop condition of I C.

First, transfer the status read command (step1). Then, input SCL clock of required bytes in step2 to read the status. 2 If the device status is BUSY when receiving the device status or the data within the memory, the I C bus may be occupied by the device in BUSY. This LSI transfers the data to the master to avoid such occupation of the bus. However, as the BUSY status still exists internally, the proper data may not be transferred in BUSY. To cope with this situation, the first byte of the transfer data (step2) is used to judge whether the transferred data is valid or invalid. After addressing from the master to the slave, if the 0 bit of the first byte of the transfer data immediately after requiring the data transfer is 0, the data transferred from the slave is valid. If the 0 bit of the first byte is 1, it shows the BUSY status. Thus, judge all the transferred data to be invalid. If this happens, retry Step1 to send commands to read the status. The first byte of the transferred data (step2) can be readable as the BUSY byte. Please read the status after sending the status read command (step1). In addition, internal statuses other than BUSY shown in Table 6. can be read. The first byte of the transferred data (step2) can be readable as the BUSY byte. Please read the status after sending the status read command (step1). In addition, internal statuses other than BUSY shown in Table.7 can be read.

Interrupt Signals to microprocessor 10.1 BUSY BUSY status detection output Signal name I/O Function BUSY O BUSY status detection output signal Remarks H: Busy, L: Not Busy This is output to indicate that the LSI is in the BUSY status. A BUSY signal outputs H until analyzing a command from the master and starting the command operation. The command input to this LSI in BUSY status is unacceptable. Connect it to the PIO port of the microcomputer. 10.2 MCHNG Tune number change detection output Signal name I/O Function Remarks MCHNG O Tune number change detection output signal H: During playing, L: At the end or stop of tune This signal outputs the information which tells that the file within the memory is being played or the file to be played is changed. Precisely, the signal outputs H during the internal decode sequence operation, and L at stop of the operation. Connect it to the interruption port of the microcomputer. 10.3 SEARCH SEARCH status detection output Signal name I/O Function SEARCH O SEARCH status detection output signal Remarks H: SEARCH, L: Not SEARCH This is output to indicate that the LSI is in the SEARCH status. A SEARCH signal becomes H at the time of memory mount, file search, TAG analysis and TOC analysis. This signal is OR of the 2-bit SEARCH status. The LSI ignores command input during SEARCH. However, it can accept only ABORT, STOP and status read commands even during SEARCH and can execute them command. Connect it to the PIO port of the microcomputer. 10.4 IRPTO Interrupt output to microcomputer Signal name I/O Function IRPTO O Interrupt output to microcomputer Remarks H: Interrupt, L: Not Interrupt This is output to indicate that the LSI is now requiring interruption to the microcomputer. Change from L to H shows that an interruption has occurred. When signage is H, it is shown that interrupt occurs.

(NTFS is not supported.) - The number of maximum playable files per folder follows the specification of FAT. Table 8. Maximum Playable Files per Folder FAT12 FAT16 FAT32 Root folder 512 512 65535 Sub folder 1024 1024 1024 The number of the maximum files which can playback in throughout the memory is 65535. The number of the maximum folders which can playback in throughout the memory is 512. (include root folder) The file or folder beyond the maximum number cannot playback. Because the pass table of the folder is made to built-in memory beforehand, the search time for next music file is shortened. Less than 256 files in the order of FAT within each folder are sorted according to UNICODE. More than 256 files, if any, will be sorted in the FAT order. The same rule is applied when sorting sub-folders. More than 100 sub-folders, if any, will be sorted in the FAT order. Sorting function can be selected valid or invalid with a command. The folder hierarchies up to 16 hierarchies whose full path including the file name is within 260 characters can be searched. 11.2 Playable file The playable file extension is *.WAV for the WAV file, *.M4A, *.3GP and *.MP4 for the AAC file, *.ASF and *.WMA for the WMA file, and *.MP3, *.MP2 and *.MP1 for the MP3 file. (There is no distinction between upper case letters and lower case letters.) Note that the file operation differs in the following cases Codec selection command: For details, please see SET_MP3 / SET_WMA / SET_AAC / SET_WAV / SET_MP3_PLAY command specifications. Attribute: Files with hidden attributes are also playable. Files with system attributes cannot be played. File name: The file name, including its size, does not depend on playability. File size: A file with file size "0" is not recognized as a playable file. 11.3 File playing sequence The file playing sequence depends on the following rules when sort function valid. See Figure 28. [1] Files of 1 to 256, in the order written to FAT (FAT order) in each folder, are sorted in the order of UNICODE. Files more than 256 are played in the FAT order. The same rule is applied when sorting sub-folders. All the folders including null ones and those to which no playable file is written are sorted (selectable setting by command). If over 256 playable files or sub-folders are contained in the folder, they are played in the order written to the FAT directory entries. The writing method of directory entries will not help understand the file play order because the method depends on the OS operation at writing. [2] When a playable file exists in the root folder (the top hierarchy), the file is to be played first. [3] After all the playable files within the root folder have been played, playable files in the folder in the lower hierarchy, if any, are played. [4] If another folder exists in the lower hierarchy, playable files within this folder are played. If not, the LSI searches other folders in the same hierarchy. If another folder exists there, the LSI plays that folder. [5] After playing all the files (MAX 1024 files), the LSI returns to the root folder as in [2] and play the files starting with the top sorted one. www.rohm.com (c) 2016 ROHM Co., Ltd.

[2] Compare the obtained folder/file names for 8 characters (16 bytes) from the beginning in UNICODE (2-byte character) and sort them in the ascending order. * [3] If there are files/folders with same character strings: follow the order of MP3, WMA, AAC and WAV when the extension is different; and, otherwise, follow the order written to FAT. [4] 101 or more files or sub-folders follow the order written to FAT. * The processing of the file name and the folder name is shown in the following. 1) When a LFN (long file name) entry exists, 2 bytes are treated as one character. 2) When no LFN entry exists, the SFN(short file name) entry is processed as follows. 2-a) When the first appeared character code is within the range of 0x00-0x7F (US-ASCII), the LSI treats one byte as one character, and adds '0x00' to the upper of the character to expand the entire character to an UNICODE. 2-b) For a case other than 2-a), practically, the LSI treats these 2 bytes as one character. *For details on LFN and SFN, see the FAT file system specifications.

If particular LUN isn't selected, the LSI mounts the device whose LUN detected first. (default) It is possible that Test Unit Ready of other LUNs is confirmed during the playback. 11.6 External HUB search When the USB connector is connected to a HUB, and a FAT-supported drive is connected ahead of the HUB at mounting the USB for this LSI, only one drive is recognized. The LSI does not support external HUBs, it cannot detect plugging/unplugging of the drive ahead of the HUB after the USB is mounted. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.

Playing files 12.1 Function For the files judged to be playable through the file search function, the LSI automatically switches the decoder using the file extension and decodes these files. Fast forward play and rewinding play operations are available. Also, repeat play and random play are available. 12.2 Playable file formats 12.2.1 MP3 file format This format supports MPEG Audio 1, 2, 2.5 and Layer 1, 2, 3. It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz, 12 kHz, 24 kHz and 48kHz. It supports bit rates of 8 to 320kbps and VBR (Variable Bit Rate). 12.2.2 WMA file format This format supports WMA Ver.9 Standard. It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz , 22.05 kHz, 44.1 kHz and 48 kHz. It supports bit rates of 5 to 384kbps and VBR (Variable Bit Rate). It does not support DRM. It supports ASF files including audio streams only. 12.2.3 AAC file format This format supports MPEG4 AAC-LC. It conforms to ITunes and 3GPP TS 26.244. It supports file types of m4a, mp42 and 3gpX. (X is an arbitrary numeric value.) ITunes is validated in the following versions: 4.*, 5.*, 6.* and 7.0-7.5. It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz, 12 kHz, 24 kHz and 48 kHz. It supports bit rates of 8 to 320kbps and VBR (Variable Bit Rate). It does not support DRM. 12.2.4 WAV file format This format supports RIFF WAVE. It supports sample rates of 8 kHz, 16 kHz, 32 kHz, 11.025 kHz, 22.05 kHz, 44.1 kHz, 12 kHz, 24 kHz and 48k Hz. If you try to play a file created in any format other than above, the LSI immediately terminates decoding it. 12.3 Playing files having damaged data If the data section of the MP3 file is damaged, the LSI plays the music data in the possible range instead of ceasing to play the entire file. It mutes the unplayable section. However, AMUTE terminal remains H output. If the data section of the WAV file is damaged, noises are output. The LSI executes other files within the playable range and stops playing. Then, it searches to the next tune. If a part of the data header is damaged, the LSI immediately terminates playing and searches to the next tune. The movement after the next tune search depends on the setting of the "SET_NEXT_MODE_ON_ERR" command. If the file's extension is playable but its file's data does not have a format supporting to the extension, the LSI immediately terminates playing and searches to the next tune. If the file does not have a file format, the LSI immediately terminates playing and searches to the next tune. However, when the file data is structured in a format other than MP3 and its file extension is *.MP3, *.MP2 or *.MP1, the LSI plays it in the silence mode basically. However, if the LSI can read any playable data, it plays the file partially. In this case, the time information which is output as the serial status also becomes unstable. The time information is then partially output but you cannot obtain the correct information. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.

When receiving the STOP command, end the present processing and shift to the initial state in each system operation mode. Playing of a file will be stopped when receiving the STOP command during Playing, a stop, and file search. Playing of a file will be stopped when receiving the STOP command during fast forward or fast back Playing. After stopping playing the file, the LSI restarts playing it from the tune being stopped. However, if the memory is removed and new one is inserted before restarting, the LSI returns to the top tune of the memory. This command select device between USB memory and SD memory card. To do this, both devices must be connected or one device is provided against the other (USB memory against SD memory card, and vice versa). Any other cases will be ignored. After the device is selected, the system operation mode remains the previous mode (before selecting) and goes to the initial state. The setting values of the individual commands remain as they are. However, those of the REPEAT and RANDOM commands return to the initial values. This command disables Watch dog Timer. Initial setting is that Watch dog Timer function is effective. This command writes "1" to STATUS WDT_RFLG when it is executed. Set up file sorting operation in a memory. rd Select N at the 3 byte from the following.

Play time is a period of time to make sound. Skip time is a period of time to skip during search. For fast forward and rewind, a cycle of {play time (M) + skip time (N) + error (O)} is repeated. The error is determined by the difference between the minimum decode unit and the rounding error between the play time and the real time requiring to search the skip time. The error varies depending on the file and memory structure. Play time is set to M[15:0]= [6th byte, 5th byte], and skip time to N[15:0]= [8th byte, 7th byte]. The unit is msec. By default, play time is 300ms=M[15:0]= [6th th byte=x01,5 byte=x2C], and skip time is 2100ms=N[15:0]= [8th byte=x08,7th byte=x34]. Specifying 0x0 sets the default. Set play time to 300ms or more, and skip time to (play timex16) or less. When it is moved by the fast rewind play in the front to the tune, the regenerated time of the first period may become shorter than setup time. th 0xL in the 4 byte sets the attenuation level during fast forward and rewind. The allowable level is -6dB X[4th byte]. Allowable setting range is from 0x00 to 0x10. By default, 0x02=-12dB is set. Setting of 0x10 is equivalent to MUTE.

To read statuses, two methods are available: to specify OFFSET of the status register map and read any bytes continuously from the OFFSET position; and to read byte data by a command without specifying the OFFSET position. Table 12. shows the status output commands. Table 13 shows the effective state of the status output command. 2 Byte data, when reading via I C, is output in Little Endian format. When read over OFFSET=0x140, OFFSET does not return to 0x00, therefore the read value turns into an unfixed value. Table 11.

System Operation MODE The LSI starts operation by setting up System Operation MODE after download of the program by IPL after a power supply and reset release. Possible operation changes with each modes of operation. Only the one mode can set up mode of operation with a command. The mode which is simultaneously different cannot be set up. A microcomputer sets up the change in System Operation MODE with a command. Please be sure to perform the changes to each mode via CONFIG mode. The changes between PLAYER mode and FILEREAD mode cannot be performed directly. The settlement of the following command is to do a re-setup because it is returned in the initial value when it passes through the CONFIG mode. REPEAT, RANDOM, SET_EQ, SET_NEXT, SET_REPRAND, SET_TAG, SET_PRM Command CHG_SYSTEM_MODE N=0x00 ; CONFIG MODE It is in the state which changes after a power supply It is the mode which performs initial setting of a system. Please change to the mode of other operation after setting up with an initial-setting command. In this mode, even if it detects insertion of a memory, mount of a memory is not performed. The mount of a memory carried out behind each mode changes. N=0x01 ; PLAYER MODE It is the mode which performs decoding play of the file in a memory. N=0x02 ; FILE Read MODE It is the mode which Reading can perform about the specific file in a memory. A specific file can be deleted. 15. Resume information This LSI outputs the information for resume function, using READ_RESUME_INFO command. Table 14. Resume information register structure Status OFFSET 0x38-0x61 The number of bytes NAME 42 Resume information data Contents This data shows the information on the file being played and on the play position. The data has a LSI-unique structure. The resume information data is data of 42 bytes. It outputs with a little endian. The above resume information has a LSI-unique structure and is used when executing resume play. Therefore, you should use the data contents as they are without rewriting. The resume function is implemented by writing the resume information read by READ_RESUME_INFO command to PLAY_RESUME command. After writing to PLAY_RESUME, the LSI automatically searches the resume. As for the action of the searches end, selectable from [Playback is started in the time when READ_RESUME_INFOcommand was forwarded], [top (Pause) in the time when READ_RESUME_INFOcommand was forwarded], [Playback is started from the front of the tune when READ_RESUME_INFOcommand was forwarded], [Stop (Pause) the front of the tune when READ_RESUME_INFOcommand was forwarded]. After reading READ_RESUME_INFO command during file play, the LSI resumes the file from the time READ_RESUME_INFO has been read. The data contents read by READ_RESUME_INFO command cannot assure the operations when executing PLAY_RESUME which has been rewritten due to the positional information within the memory. If the resume information does not match because of change of memory, the LSI starts searches front file of memory. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.

Can disable WDT using DIS_WDT command. Once WDT is disabled, it cannot be enabled until reset is input. When WDT, in the valid status, detects a hang-up within the LSI regardless of external situations (on the microcomputer), the LSI resets the system internally. To monitor whether the LSI is reset by WDT from the master microcomputer (external), use SET_WDT command to write H to STATUS WDT_RFLG and monitor this status. After reset, this status is read as L. This helps you judge that WDT has reset the LSI by reading out L when reading the status regularly after writing H using SET_WDT command. www.rohm.com (c) 2016 ROHM Co., Ltd. All rights reserved.
