29.3. Capture/Compare Modules
Each module can be configured to operate independently in one of six operation modes: Edge-triggered
Capture, Software Timer, High Speed Output, Frequency Output, 8 to 11-Bit Pulse Width Modulator, or 16-
Bit Pulse Width Modulator. Each module has Special Function Registers (SFRs) associated with it in the
CIP-51 system controller. These registers are used to exchange data with a module and configure the
module's mode of operation. Table 29.2 summarizes the bit settings in the PCA1CPMn and PCA1PWM
registers used to select the PCA1 capture/compare module’s operating mode. All modules set to use 8, 9,
10, or 11-bit PWM mode must use the same cycle length (8-11 bits). Setting the ECCF1n bit in a
PCA1CPMn register enables the module's CCFn interrupt.

Notes:
1. X = Don’t Care (no functional difference for individual module if 1 or 0).
2. A = Enable interrupts for this module (PCA1 interrupt triggered on CCFn set to 1).
3. B = Enable 8th, 9th, 10th or 11th bit overflow interrupt (Depends on setting of CLSEL1[1:0]).
4. C = When set to 0, the digital comparator is off. For high speed and frequency output modes, the
5. D = Selects whether the Capture/Compare register (0) or the Auto-Reload register (1) for the associated
6. E = When set, a match event will cause the CCFn flag for the associated channel to be set.
7. All modules set to 8, 9, 10 or 11-bit PWM mode use the same cycle length setting.
associated pin will not toggle. In any of the PWM modes, this generates a 0% duty cycle (output = 0).
