TC62D722CFG/CFNG
1. Explanation of the function (Basic data input pattern)
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
Number of SCK pulses
at TRANS=”H” Note3,4
Operation
S0
0,1
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
S1
2,3
2. The automatic output open/short detection result data is transmitted to the 16-bit shift register. Note2
3. PWM output start.
S2
7,8
Input of the output ON/OFF data. (When this function is not used, this input is unnecessary.)
S3
9,10
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
S4
11,12
Reset of the internal PWM counter.
S5
13,14
Input of the state setting data (1).
S6
15,16
Input of the state setting data (2).
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"
If SCK is "H" when changing TRANS into "H", Please make SCL "H" when changing TRANS into "L"
