Description
7
CF
PCA Counter Overflow flag
Set by hardware when the counter rolls over. CF flags an interrupt if bit ECF in
CMOD is set. CF may be set by either hardware or software but can only be
cleared by software.
6
CR
PCA Counter Run control bit
Must be cleared by software to turn the PCA counter off.
Set by software to turn the PCA counter on.
5
-
Reserved
The value read from this bit is indeterminate. Do not set this bit.
4
CCF4
PCA Module 4 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
3
CCF3
PCA Module 3 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
2
CCF2
PCA Module 2 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
1
CCF1
PCA Module 1 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
0
CCF0
PCA Module 0 interrupt flag
Must be cleared by software.
Set by hardware when a match or capture occurs.
