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 26 &

Table 27)

Table 26. CCAPnH: PCA Modules Capture/Compare Registers High
