2.2.2.2
The OPTION_REG register is a readable and writable
register, which contains various control bits to configure
the
assignable register known also as the prescaler), the
External INT Interrupt, TMR0 and the weak pull-ups on
PORTB.

RBPU: PORTB Weak Pull-up Enable bit
1 = PORTB weak pull-ups are disabled
0 = PORTB weak pull-ups are determined by alternate function or TRISBn bit value
INTEDG: Interrupt Edge Select bit
1 = Interrupt on rising edge of RB0/INT pin
0 = Interrupt on falling edge of RB0/INT pin
T0CS: TMR0 Clock Source Select bit
1 = Transition on RA4/T0CKI pin
0 = Internal instruction cycle clock (CLKOUT)
T0SE: TMR0 Source Edge Select bit
1 = Increment on high-to-low transition on RA4/T0CKI pin
0 = Increment on low-to-high transition on RA4/T0CKI pin
PSA: Prescaler Assignment bit
1 = Prescaler is assigned to the WDT
0 = Prescaler is assigned to the Timer0 module
