DC Motor and Voice Coil Motor Drive Methods (Channel 3, 4)
When channel 3 or channel 4 is used to drive a DC or voice coil motor, the drive polarity is set with the serial data.
Setting Procedure
(1) Set PWM signal input(channel 3 to 4) to CLK2/PWM select with the serial data.
→This sets up the signal input from the CLK2/PWM pin to be accepted as a PWM signal for channel 3 or channel 4.
( It doesn't accept as CLK signal.)
(2) If the output is to be controlled by PWM control, set up PWM mode and PWM signal allocation with the serial data.
(3) Set the drive polarity for each channel with the serial data.
(4) If the output is to be controlled by PWM control, input the CLK2/PWM signal to the PWM pin.
The following tables describe the correspondence between the PWM signal and the output logic.
