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 mode.
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 Flag. ECF = 1 enables CF bit
in CCON to generate an interrupt; ECF = 0 disables that function.
