Description
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.
CR
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.
CCF4
PCA Module 4 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
CCF3
PCA Module 3 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
CCF2
PCA Module 2 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
CCF1
PCA Module 1 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
CCF0
PCA Module 0 Interrupt Flag. Set by hardware when a match or
capture occurs. Must be cleared by software.
