Description
PCA Timer/Counter Overflow flag
Set by hardware when the PCA Timer/Counter rolls over. This
generates a PCA interrupt request if the ECF bit in CMOD register
is set.
Must be cleared by software.
PCA Timer/Counter Run Control bit
Clear to turn the PCA Timer/Counter off.
Set to turn the PCA Timer/Counter on.
Reserved
The value read from these bist are indeterminate. Do not set these
bits.
PCA Module 1 Compare/Capture Flag
Set by hardware when a match or capture occurs. This generates a
PCA interrupt request if the ECCF 1 bit in CCAPM 1 register is set.
Must be cleared by software.
PCA Module 0 Compare/Capture Flag
Set by hardware when a match or capture occurs. This generates a
PCA interrupt request if the ECCF 0 bit in CCAPM 0 register is set.
Must be cleared by software.
