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 this bit is indeterminate. Do not set this bit.
PCA Module 4 Compare/Capture flag
Set by hardware when a match or capture occurs. This generates a PCA
interrupt request if the ECCF 4 bit in CCAPM 4 register is set.
Must be cleared by software.
PCA Module 3 Compare/Capture flag
Set by hardware when a match or capture occurs. This generates a PCA
interrupt request if the ECCF 3 bit in CCAPM 3 register is set.
Must be cleared by software.
PCA Module 2 Compare/Capture flag
Set by hardware when a match or capture occurs. This generates a PCA
interrupt request if the ECCF 2 bit in CCAPM 2 register is set.
Must be cleared by software.
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.
