There are two additional registers associated with each of the PCA modules. They are CCAPnH
and CCAPnL and these are the registers that store the 16-bit count when a capture occurs or a
compare should occur. When a module is used in the PWM mode these registers are used to
control the duty cycle of the output (See Table 6-8 & Table 6-9)
Table 6-8.
CCAPnH: PCA Modules Capture/Compare Registers High
Table 6-9.
CCAPnL: PCA Modules Capture/Compare Registers Low
Table 6-10.
CH: PCA Counter High
Table 6-11.
CL: PCA Counter Low
6.3.1
PCA Capture Mode
To use one of the PCA modules in the capture mode either one or both of the CCAPM bits
CAPN and CAPP for that module must be set. The external CEX input for the module (on port 1)
is sampled for a transition. When a valid transition occurs the PCA hardware loads the value of
the PCA counter registers (CH and CL) into the module's capture registers (CCAPnL and
CCAPnH). If the CCFn bit for the module in the CCON SFR and the ECCFn bit in the CCAPMn
SFR are set then an interrupt will be generated (Refer to Figure 6-6).
