My TDA7318 audio mixer chip still makes some trouble: It seems to ignore all commands I send to it. On pages 9–11 of the datasheet, eight different commands are described, one byte per command. A command of "N bytes" + a stop byte at the end must be sent to the chip, but there is no mention of how much N must be:
The device seems not to have the usual registers. Here is an overview of the corresponding commands:
Now here is my question: Do I have to send all eight command bytes to the chip every time I'd like to change something?
