描述
ML226xx系列是内置有4Mbit～32Mbit Flash存储器的语音合成LSI。由于内置了大容量存储器，因此非常适用于语音操作指导等需要长时间播放语音的应用。此外，该系列产品还支持通过微控制器改写Flash存储器。产品采用实现高音质的HQ-ADPCM、16位D/A转换器和低通滤波器，并内置用来直接驱动扬声器的1.0W单声道扬声器放大器。语音输出所需的功能已经全部集成于1枚芯片中，因此仅需增加本LSI，即可轻松实现语音功能。

●Continuous playback timing by START command

[ ] When making continuous playbacks, send the START command for the next phrases within the specified time period

(tcm) after the NCR of the corresponding channel changes to "H" level.

[ ] When the playback is not continuous, input the START command for the next phrases after confirming the playback is

completed by RDSTAT command, etc.

●Continuous playback timing by MUON command

[ ] When making continuous playbacks, input the MUON/PLAY/START command for the next phrases within 10ms

(tcm) after the NCR of the corresponding channel changes to "H" level.When the playback is not continuous, input

the MUON/PLAY/START command for the next phrases after confirming the playback is completed by RDSTAT

command, etc.

●Repeat playback setting/release timing by SLOOP/CLOOP command

[ ] The SLOOP command is valid only during playback. After the PLAY command is input, input the SLOOP command

within the specified period (tcm) after the NCR of the corresponding channel becomes "H" level.

■Command

●Command list

[ ] Do not enter command that is not described in this manual. Enter the command with the CBUSYB "H".

●Description of Command Functions

◆ PUP command

[ ] Even if two-times input modes are used for the I2C interface, one-time input is used for the slave address input. If the

slave address matches, ACK is returned. If the slave address does not match, NACK is returned. The command is

input two-times.

◆ 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).

[ ] 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.

[ ] 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.
