PCA Counter/Timer Overflow Flag.
Set by hardware when the PCA Counter/Timer overflows from 0xFFFF to 0x0000.
When the Counter/Timer Overflow (CF) interrupt is enabled, setting this bit causes the
CPU to vector to the PCA interrupt service routine. This bit is not automatically cleared
by hardware and must be cleared by software.
PCA Counter/Timer Run Control.
This bit enables/disables the PCA Counter/Timer.
0: PCA Counter/Timer disabled.
1: PCA Counter/Timer enabled.
These bits are set by hardware when a match or capture occurs in the associated PCA
Module n. When the CCFn interrupt is enabled, setting this bit causes the CPU to
vector to the PCA interrupt service routine. This bit is not automatically cleared by
hardware and must be cleared by software.
