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.

Internal data latching

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.
