Data I/O Techniques
CCB Technique
Sanyo audio ICs input and output data using the Sanyo CCB (computer control bus) standard, which is a serial bus
format. This IC uses an 8-bit address CCB and uses the following addresses.

Data Output Timing
A10596
Note:The DO pin is normally left open.
Since the DO pin is an n-channel open drain pin, the time required for the data to change from the low level to the high level depends on the value of
the pull-up resistor.
