4.2.2.2
The OPTION Register is a readable and writable regis-
ter, which contains various control bits to configure the
TMR0/WDT prescaler, the External INT Interrupt,
TMR0 and the weak pull-ups on GPIO.

OPTION Register
GPPU: Weak Pull-up Enable bit
1 = Weak pull-ups disabled
0 = Weak pull-ups enabled (GP0, GP1, GP3)
INTEDG: Interrupt Edge Select bit
1 = Interrupt on rising edge of GP2/T0CKI/AN2/INT pin
0 = Interrupt on falling edge of GP2/T0CKI/AN2/INT pin
T0CS: TMR0 Clock Source Select bit
1 = Transition on GP2/T0CKI/AN2/INT pin
0 = Internal instruction cycle clock (CLKOUT)
T0SE: TMR0 Source Edge Select bit
1 = Increment on high-to-low transition on GP2/T0CKI/AN2/INT pin
0 = Increment on low-to-high transition on GP2/T0CKI/AN2/INT pin
PSA: Prescaler Assignment bit
1 = Prescaler is assigned to the WDT
0 = Prescaler is assigned to the Timer0 module
PS<2:0>: Prescaler Rate Select bits

To achieve a 1:1 prescaler assignment for
the TMR0 register, assign the prescaler to
the Watchdog Timer by setting bit PSA
(OPTION<3>).
