Name
Timer0 module.
A dedicated 16-bit WDT postscaler is available. See Section 14.5 “Watchdog Timer (WDT)” for more
information.
RABPU: PORTA/PORTB Pull-up Enable bit
1 = Pull-ups on PORTA/PORTB are disabled
0 = Pull-ups on PORTA/PORTB are disabled by individual WPUAx control bits
INTEDG: Interrupt Edge Select bit
1 = Interrupt on rising edge of INT pin
0 = Interrupt on falling edge of INT pin
T0CS: TMR0 Clock Source Select bit
1 = Transition on T0CKI pin
0 = Internal instruction cycle clock (F
T0SE: TMR0 Source Edge Select bit
1 = Increment on high-to-low transition on T0CKI pin
0 = Increment on low-to-high transition on T0CKI pin
PSA: Prescaler Assignment bit
1 = Prescaler is assigned to the WDT
