7
EINTF
1 - Enable the interrupt flags (INTF) in the Status Register to generate an
interrupt.
6
E_COMP 1 - Enable the comparator when set
5
CAP_PE 1 - Enable Capture Mode, a positive edge on the CEXn pin.
4
CAP_NE 1 - Enable Capture Mode, a negative edge on the CEXn pin.
3
MATCH 1 - A match from the comparator sets the INTF bits in the Status Register.
2
TOGGLE 1 - A match on the comparator results in a toggling output on CEXn pin.
01 Enable PWM Mode (x8), fixed frequency. Enable the CEXn pin as a
PWM output.
1-0
PWM[1:0]
10 Enable PWM Mode (x8) with programmable frequency. Enable the
CEXn pin as a PWM output.
11 Enable PWM Mode (x10 or x16), fixed frequency. Enable the CEXn pin
as a PWM output.
