This bit enables 16-bit mode when Pulse Width Modulation mode is enabled.
0: 8 to 11-bit PWM selected.
1: 16-bit PWM selected.
This bit enables the comparator function for PCA1 module n when set to 1.
This bit enables the positive edge capture for PCA1 module n when set to 1.
This bit enables the negative edge capture for PCA1 module n when set to 1.
Match Function Enable.
This bit enables the match function for PCA1 module n when set to 1. When enabled,
matches of the PCA1 counter with a module's capture/compare register cause the
CCFn bit in PCA1MD register to be set to logic 1.
Toggle Function Enable.
This bit enables the toggle function for PCA1 module n when set to 1. When enabled,
matches of the PCA1 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 PCA1 module n when set to 1. When enabled, a
pulse width modulated signal is output on the CEXn pin. 8 to 11-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.
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.
