23.2. 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-Bit Pulse Width Modulator, or 16-Bit Pulse Width Modu-
lator. 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 23.2 summarizes the bit settings in the PCA0CPMn registers used to select the PCA0 capture/compare mod-
ule’s operating modes. Setting the ECCFn bit in a PCA0CPMn register enables the module's CCFn interrupt. Note:
PCA0 interrupts must be globally enabled before individual CCFn interrupts are recognized. PCA0 interrupts are
globally enabled by setting the EA bit (IE.7) and the EPCA0 bit (EIE1.3) to logic 1. See Figure 23.3 for details on the
PCA interrupt configuration.
