Comparator

Edge

All_Edge

The comparator will trigger an interrupt on both the rising edge or falling edge

Rising_Edge

The comparator will trigger an interrupt on the rising edge

Falling_Edge

The comparator will trigger an interrupt on the falling edge

GPC_PWM

Disable

Comparator does not control all PWM outputs

Enable

Comparator controls all PWM outputs (ICE does NOT support.)

TMx_Source

16MHZ

When tm2c[7:4]= 0010, TM2 clock source = IHRC = 16MHZ

When tm3c[7:4]= 0010, TM3 clock source = IHRC = 16MHZ

32MHZ

When tm2c[7:4]= 0010, TM2 clock source = IHRC*2 = 32MHZ

When tm3c[7:4]= 0010, TM3 clock source = IHRC*2 = 32MHZ

(ICE does NOT support.)
