Symbol
WDTD
Function
Initial/Reload value in Watchdog Timer. New value won’t be effective until WDT is set.
Symbol
CF
Function
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 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.
Not implemented, reserved for future use.
Note:
User should not write ‘1’s to reserved bits. The value read from a reserved bit is indeterminate.
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.
