LC75010W
CCB Control System Timing and Data Format
The LC75010W uses a CCB (Computer Control Bus) serial bus, which is a SANYO-developed bus format.
The input serial data consists of a total of (8 + DI + C) bits. Here, the first 8 bits are the CCB address, the next DI bits are
the data bits, and the last C bits are control bits. The output serial data consists of (8 + DO) bits. Here, the first 8 bits are
the CCB address and the next DO bits are the output data bits. Serial data can be input or output after power has been
applied, the crystal oscillator and PLL circuits have stabilized, and a reset has been applied.

Serial Data Input
CL: Normally high
Serial Data Output
CL: Normally high
CL: Normally low
CL: Normally low
Note: Since the DO pin is an n-channel open-drain output, the data transition times (tDC and tDH) differ depending on the value of the pull-up resistor used.
