Bit	Bit			Function
Number	Mnemonic
7	CIDL	PCA Timer/Counter Idle Control:
		CIDL = 1 disables the PCA timer/counter during idle mode. CIDL = 0
		allows the PCA timer/counter to run during idle mode.
6	WDTE	Watchdog Timer Enable:
		WDTE = 1 enables the watchdog timer output on PCA module 4.
		WDTE = 0 disables the PCA watchdog timer output.
5:3	—	Reserved:
		The values read from these bits are indeterminate. Write zeros to these
		bits.
2:1	CPS1:0	PCA Timer/Counter Input Select:
		CPS1 CPS0
		0	0	FOSC /12
		0	1	FOSC /4
		1	0	Timer 0 overflow
		1	1	External clock at ECI pin (maximum rate = FOSC /8 )
0	ECF	PCA Timer/Counter Interrupt Enable:
		ECF = 1 enables the CF bit in the CCON register to generate an interrupt
		request.
