175 / 178 page  FEDL22Q53X-02 ML22Q53X ◆AMODE command [ ] To perform power-down under a setting condition that differs from the power-up condition of the analog unit, set the AMODE command to set the power-down condition again. [ ] To power up the analog part, set the CVOL command to 00h (initial value) and then enter the AMODE command. [ ] When using analog mixing from the AIN pin, set DAMP = "0" (Class AB amplifier is used). In this LSI, select DAMP = "0" (Class AB amplifier is used). [ ] Input the sound signals to the AIN pin after CBUSYB pin becomes "H" by the AMODE command. [ ] When using a Class D amplifier with speaker amplifier outputs, set it to the power-up state (AEN1/AEN0= "01") or the power-down state (AEN1/AEN0= "00"). If DAMP = "1" is selected, do not set AEN1= "1". ◆AVOL command [ ] AV5-AV2=1h and 2h are prohibited. ◆FDIRECT command [ ] The FDIRECT command controls accesses to the flash memory using the clock synchronous serial interface.Input the command after inputting the PUP command. [ ] Do not enter this command because this command is ignored when this command is entered from the I 2C interface. [ ] To cancel the flash memory access mode, insert a reset (RESETB = "L") and conduct initialization or turn off the power supply. ◆START command [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3). Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆STOP command [ ] The STOP command can be input regardless of the status of the NCR during playback operation. However, following the elapse of CBUSYB "L" level output time 3 (tCB3), input the next command after confirming that the BUSYB signal becomes "H". If the BUSYB signal does not become "H", enter the STOP command again. [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3). Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆MUON command [ ] Set the silence setting (M7-M0) to 04h or more (tmu>=20ms). [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3). Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆SLOOP command [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3). Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆CLOOP command [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3).Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆CVOL command [ ] Be sure to specify one of the channels for the channel setting (CH0-CH3). When multiple channels are specified, the volume of the specified channels is set. Do not input it to "0" (all “0”) with specifying nothing. If it is input with specifying nothing (all "0"), the command is ignored. ◆RDSTAT commnad [ ] When reading the status of the second byte after command input, set the SI pin to "L". ◆RDVER command [ ] When reading the status of the second byte after command input, set the SI pin to "L". ◆RDERR command [ ] When reading the status of the second byte after command input, set the SI pin to "L". [ ] If the outputs of misoperation detection and failure detection are selected by OUTSTAT command, and the read data is all "L" even though STATUS1 or STATUS2 pin is "H", the read data cannot be read normally. Be sure to read it again. ◆SAFE command [ ] The initial value is the operation stop state ("0"). When this bit is set to "1", operation starts. [ ] *1 Do not set WDTEN and RSTEN to "1" at the same time. If these bits are set to "1" at the same time, only the RSTEN bit is set to "1". 175/178 |
