This bit enables 16-bit mode when Pulse Width Modulation mode is enabled.
0: 8-bit PWM selected.
1: 16-bit PWM selected.
Comparator Function Enable.
This bit enables the comparator function for PCA module n when set to 1.
Capture Positive Function Enable.
This bit enables the positive edge capture for PCA module n when set to 1.
Capture Negative Function Enable.
This bit enables the negative edge capture for PCA module n when set to 1.
Match Function Enable.
This bit enables the match function for PCA module n when set to 1. When enabled,
matches of the PCA counter with a module's capture/compare register cause the CCFn
bit in PCA0MD register to be set to logic 1.
Toggle Function Enable.
This bit enables the toggle function for PCA module n when set to 1. When enabled,
matches of the PCA counter with a module's capture/compare register cause the logic
level on the CEXn pin to toggle. If the PWMn bit is also set to logic 1, the module oper-
ates in Frequency Output Mode.
Pulse Width Modulation Mode Enable.
This bit enables the PWM function for PCA module n when set to 1. When enabled, a
pulse width modulated signal is output on the CEXn pin. 8-bit PWM is used if PWM16n
is cleared; 16-bit mode is used if PWM16n is set to logic 1. If the TOGn bit is also set,
the module operates in Frequency Output Mode.
Capture/Compare Flag Interrupt Enable.
This bit sets the masking of the Capture/Compare Flag (CCFn) interrupt.
0: Disable CCFn interrupts.
1: Enable a Capture/Compare Flag interrupt request when CCFn is set.
