Writing a logic one to a INDEPx bit configures a pair of the PWM outputs as two independent PWM
channels. Each PWM output has its own PWM value register operating independently of the other
channels in independent channel operation.
Writing a logic zero to a INDEPx bit configures the PWM output as a pair of complementary channels.
The PWM pins are paired as shown in
The complementary channel operation is for driving top and bottom transistors in a motor drive circuit,
such as the one in
