Pulse-Width Modulator for Motor Control (PWMMC)
12.5 Output Control
This subsection discusses output control.
12.5.1 Selecting Six Independent PWMs or Three Complementary PWM Pairs
The PWM outputs can be configured as six independent PWM channels or three complementary channel
pairs. The option INDEP determines which mode is used (see
complementary operation is chosen, the PWM pins are paired as shown in
one pair is then determined by one PWM value register. This type of operation is meant for use in motor
drive circuits such as the one in
