4.2.2.2
The Option register is a readable and writable register,
which contains various control bits to configure the
TMR0/WDT prescaler, the external RB0/INT interrupt,
TMR0 and the weak pull-ups on PORTB.

RBPU: PORTB Pull-up Enable bit
1 = PORTB pull-ups are disabled
0 = PORTB pull-ups are enabled by individual port latch values
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/CMP2 pin
0 = Internal instruction cycle clock (CLKOUT)
T0SE: TMR0 Source Edge Select bit
1 = Increment on high-to-low transition on RA4/T0CKI/CMP2 pin
0 = Increment on low-to-high transition on RA4/T0CKI/CMP2 pin
PSA: Prescaler Assignment bit
1 = Prescaler is assigned to the WDT
0 = Prescaler is assigned to the Timer0 module
