First, transfer the status read command (step1). Then, input SCL clock of required bytes in step 2 to read the status. When the device is BUSY at reception of device status or memory data, the I2C bus may possibly be occupied by the device during BUSY. This LSI transfers the bus to the master so as not to generate such bus occupation. However, as a BUSY state still exists inside of the system, appropriate data may not be transferred during BUSY. Therefore, the first byte of transfer data (Step2) is used to judge the transfer data is enabled/disabled. When specifying addresses from the master to the slave and the first byte of the transfer data immediately after data transfer is required is 0x00, transfer data from the slave is enabled. If the first byte is 0xFF, it shows the BUSY state. Therefore, the transfer data should be disabled. If this happens, retry command transfer at Step 1 to read out the status. Figure 14 shows the relationship between the transfer data and BUSY. * For further information on BUSY, see Chapter 17. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

(Upper case letters and lower case letters are not distinguished.) Note that the file operation differs in the following cases: (1) SEL_MP3: See SEL_MP3 for details. (2) Attribute: AAC/WMA/MP3 file whose attribute is masked can be played. A file with system attributes cannot be played. (3) Data destroyed file: When the data section of AAC/WMA/MP3 file is destroyed, the music data of the file can be played as much as possible rather than disabling to play the entire file. The section which cannot be played is muted. However, AMUTE terminal remains the H output level. When the header section of WMA and AAC file is destroyed, it plays next. (4) File name: A file name and its size do not depend on playing. (5) Extension: When file data is configured in the non-AAC format and its file extension is *.M4A, *.3GP and *.MP4 the state is play next. When file data is configured in the non-WMA format and its file extension is *.WMA, or *.ASF, the state is play next. When file data is configured in the non-MP3 format and its file extension is *.MP3, *.MP2 or *.MP1, the state is silent playing basically. If playable data can be read, only a part of the file can be played. The information on time required to output serial status also becomes uncertain. Then, partial output is done but the correct time information is not output. (6) File size: When file size is “0”, the file do not recognize at AAC/WMA/MP3 files. (7) This LSI corresponds to the AAC file encoded by iTunes. The versions of iTunes checked operation are 4.*, 5.*, 6.*, and 7.0 to 7.5. The AAC file encoded with other software may cause fault, such as being in the middle of reproduction and skipping to next. (8) When the extension of WMA file is *.ASF, this LSI corresponds to the ASF file of only an audio stream. 20.3 Playing sequence The playing sequence of supported files is determined based on the following rules. See Figure24. (1) Folders are sorted in the order written in FAT (in the order of FAT), and files 1 to 100 are sorted in the order of UNICODE. (*See Chapter 20.4.) Files over 100 are sorted in the order of FAT. Folders over 100 are sorted in the same manner. Files are sorted following SEL_MP3. Folders are sorted including null folders and those in which supported files are not written. Within each folder, supported files over 100 and folders over 100 are played in the order written to the FAT directory entry. Since how to write to the directory entry depends on the OS (Operating System) processing to write to the memory, you cannot understand the file playing sequence. (2) When supported files exist in the root folder (the highest layer), the files are played first. (3) When all the files in the root folder have been played, those in the folder under the root folder, if any, are played. (4) When a folder is layered under that, files in the folder are played. When not, the master searches any other folders at the same layer and plays the one, if any. (5) After playing all the files, the master returns to the root folder as described in (2) and start playing with the first sorted file. 20.4 Folder/file sort Folders and files are sorted in the following sequence using this LSI. (1) Obtain up to 100 files and 100 folders in the order written to FAT. (2) Compare the obtained folder/file names up to 14 characters (including filename extensions) and sort them in the ascending order.* (3) When the same strings are generated, follow the order written to FAT. (4) For 101 or more folders and files, follow the order written to FAT. * The processing of the file name and the folder name is shown in the following. 1)When the LFN(long file name) entry exists, folder/filename is processed as one character in two bytes. 2)When the LFN entry doesn't exist, the SFN(short file name) entry is processed as follows. 2-a) When character-code that appears first is ≧0x80 ,It’s treated as the first byte of two byte character. Byte data afterwards is treated as the second byte of two byte character-code, and treated by two bytes as one character. 2-b) When the case that doesn't apply to 2-a) ,that is, the character-code appears first is installed within the range of 0x00-0x7F(US-ASCII) One byte is treated as one character. '0x00' is added and enhanced to Unicode. Please confirm the specification of the FAT filesystem about details of LFN and SFN. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

(MODE2 and MODE3) If particular LUN isn’t selected, the LSI mounts the device whose LUN detected first. (default) When the multi-card reader is connected, the LSI can recognize device which connected to the card-reader by selecting LUN. But after the device is mounted, it’s impossible to recognize states whether the device connected to the card-reader is inserted or removed. 20.6 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. 21.

(1) KEY_COL1 to 3 output waveforms at timing as shown in Figure25. (2) By pressing KEY switch, KEY_ROW 1 to 4 are set to L at timing when KEY_COL 1 to 3 are L. (3) When detecting L input from KEY_ROW 1 to 4 three times, the master judges that KEY has been pressed. Then, the master starts judging status of held KEY. (4) When pressed KEY’s decision (L input from KEY_ROW 1 to 4 three times) is detected consecutive 15 times, the master judges that KEY Mode is Hold Mode. (5) When KEY release is detected in judging status of hold KEY, the master judges that KEY Mode is Single Mode. Then, the master starts the KEY operation. (6) When Hold Mode is detected, the master starts the KEY operation in Hold Mode. When KEY release is detected in Hold Mode, the master finish the KEY operation. The keys corresponding to Hold Mode are FF, FB, VOL+, and VOL-. Figure 27 KEY SCAN Waveform. Note 1: Based on the above sequence, the master determines that KEY is pressed and starts the operation of the pressed KEY, pressing multiple KEYs at the same time will produce different operations depending on the KEY combinations. Therefore, you cannot regulate the operation sequence correctly even simultaneously pressing multiple KEYs will not cause any problems. In Hold Mode, Other pressed KEY is disregarded. Note 2: Because the KEY input does not have a buffering function, KEY inputs other than those described below are ignored. www.rohm.com © 2012 ROHM Co., Ltd. All rights reserved.

After RESET, WDT function is enabled on MODE1, MODE2 and MODE3. WDT is enabled always on MODE1. On MODE2 and MODE3, WDT function can disable by command “SET_WDT”(0x5A,0x00). After WDT function is disabled, this function cannot enable until a reset from external pin. When WDT function is enabled and system is hang-up, Watchdog Timer function generates RESET. When you want to watch RESET of WDT from master micro controller, write command “SET_WDT”(0x5A,0x01). After write command “SET_WDT”(0x5A,0x01), status “WDT_RFLG” is “1”. “WDT_RFLG” is bit6 of STATUS5(offset;x04). This status is “0” after RESET. Therefore, when this status returned to “0” from “1”, this system generated a reset. 25.
