Function
Serial data input pin.
This pin inputs 12-bit length serial data.
This pin outputs MSB bit data of 12-bit shift register.
Shift clock input pin.
The input signal from the DI pin is inputted to a 12-bit
shift register on the rising edge of the shift clock.
If input “H” level to LD pin, the data of shift register is
loaded to the decoder and the register for D/A output.
