Control System Timing and Data Format

The stipulated serial data must be input to the CL, DI, and CE pins to control the LC75348 and LC75348M. The data

structure has a total of 40 bits, of which 8 bits are address and 32 bits are data.

• Address code (B0 to A3)

The data has an 8-bit address code, which allows this IC to be used with the SANYO CCB serial bus.

• Control code allocation

Address code (LSB)
