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。

ML22Q66X

◆ 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".
