Serial Interface

The NJU6060 interface with MPU by Serial Interface, control for LED.

Note1) Data is not concerned with the signal of CSb but is read into the internal shift register by the rising edge of CLK.

Note2) The contents of a shift register are read into the internal instruction decoder by the rising edge of CSb.

note3) An instruction and data should surely input 8 bits. In case of entering over than 8 bits data, valid data is last 8 bits

data.
