Serial Data I/O Scheme
1. CCB Format
The figure shows the Sanyo audio LSI serial bus format. Data is input and output over a CCB (computer control
bus). This LSI uses an 8-bit address CCB format.

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