Mnemonic Description

PCA Timer/Counter Overflow flag

CF

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

CR 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

4

CCF4

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

3

CCF3

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

2

CCF2

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

1

CCF1

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

0

CCF0

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.
