1. Explanation of the function
S0 command (The PWM data is transmitted to the PWM data register 1.)
S1 command (The PWM data is transmitted to the PWM data register 2 or 3.)
S2 command (Input of the output ON/OFF data.)
S3 command (The output open/short detection functions manual operation is executed.)
S4 command (Reset of the internal PWM counter.)
S5 command (Input of the state setting data (1).)
S6 command (Input of the state setting data (2).)
Data input is done with the SIN pin and the SCK pin.Command selection is done with the SCK pin and the TRANS pin.
About the operation of each command
Command
Note1: Transmitted register changes by a PWM counter synchronization setting.
Note2: This operation is performed when the output open/short detection function is “Active” setting.
Note3: Other SCK numbers are disregarded.
Note4: If SCK is "L" when changing TRANS into "H", Please make SCL "L" when changing TRANS into "L"

The PWM data in the 16-bit shift register is transmitted to the PWM data register 1.
1. The PWM data in the PWM data register 1 is transmitted to the PWM data register 2 or 3. Note1
2. The automatic output open/short detection result data is transmitted to the 16-bit shift register. Note2
3. PWM output start.
Input of the output ON/OFF data. (When this function is not used, this input is unnecessary.)
The manual output open/short detection functions are executed. Note2
The manual output open/short detection result data is transmitted to the 16-bit shift register. Note2
Reset of the internal PWM counter.
Input of the state setting data (1).
Input of the state setting data (2).
