2. About the operation of each command

2-1-1) S0 command (The PWM data is transmitted to the PWM data register 1.)

Operation) In the number of SCK pulses at TRANS="H" is 0 or 1, the following operation is executed.

The PWM data in the 16-bit shift register is transmitted to the PWM data register 1.

It is necessary to repeat this command 16 times to input the PWM data of

0
