Description
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.
PCA counter run control bit. Set by software to turn the PCA counter
on. Must be cleared by software to turn the PCA counter off.
Reserved for future use. Should be set to ‘0’ by user programs.
PCA Module 4 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
PCA Module 3 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
PCA Module 2 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
PCA Module 1 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
PCA Module 0 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
Description
Reserved for future use. Should be set to ‘0’ by user programs.
Enable Comparator. ECOMn = 1 enables the comparator function.
Capture Positive, CAPPn = 1 enables positive edge capture.
Capture Negative, CAPNn = 1 enables negative edge capture.
Match. When MATn = 1 a match of the PCA counter with this module’s
compare/capture register causes the CCFn bit in CCON to be set,
flagging an interrupt.
