Description
Counter Idle Control: CIDL = 0 programs the PCA Counter to continue
functioning during Idle mode. CIDL = 1 programs it to be gated off
during idle.
Watchdog Timer Enable: WDTE = 0 disables watchdog timer function
on module 4. WDTE = 1 enables it.
Reserved for future use. Should be set to ‘0’ by user programs.
PCA Count Pulse Select (see
PCA Enable Counter Overflow Interrupt: ECF = 1 enables CF bit in
CCON to generate an interrupt. ECF = 0 disables that function.
