	Bit					Bit					Function
	Number			Mnemonic
	7			CF			PCA Timer/Counter Overflow Flag:
							Set by hardware when the PCA timer/counter rolls over. This generates
							an interrupt request if the ECF interrupt enable bit in CMOD is set. CF
							can be set by hardware or software but can be cleared only by software.
	6			CR			PCA Timer/Counter Run Control Bit:
							Set and cleared by software to turn the PCA timer/counter on and off.
	5			—			Reserved:
							The value read from this bit is indeterminate. Write a zero to this bit.
	4:0			CCF4:0			PCA Module Compare/Capture Flags:
							Set by hardware when a match or capture occurs. This generates a PCA
							interrupt request if the ECCFx interrupt enable bit in the corresponding
							CCAPMx register is set. Must be cleared by software.

NOTES:

1.This table shows the CCAPMx register bit combinations for selecting the operating modes of the PCA compare/capture modules. Other bit combinations are invalid. See Figure 9-9 for bit definitions.

2.x = 0–4, X = Don’t care.

3.For PCA WDT mode, also set the WDTE bit in the CMOD register to enable the reset output signal.
