The OPTION register, shown in Register 2-2, is a
readable and writable register, which contains various
control bits to configure:
• External INT interrupt
• Timer0
• Weak pull-ups

OPTION register
WPUEN: Weak Pull-up Enable bit
1 = All weak pull-ups are disabled (except MCLR, if it is enabled)
0 = Weak pull-ups are enabled by individual WPUx 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: Timer0 Clock Source Select bit
1 = Transition on RA4/T0CKI pin
0 = Internal instruction cycle clock (F
T0SE: Timer0 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 inactive and has no effect on the Timer0 interrupt rate
0 = Prescaler is active and affects the Timer0 interrupt rate
