bit 3
bit 2:0
The OPTION_REG register is a readable and writable register which contains various control bits
to configure the TMR0/WDT prescaler, the External INT Interrupt, TMR0, and the weak pull-ups
on PORTB.
Register 11-1: OPTION_REG Register
bit 7
RBPU
1 = Weak pull-ups are disabled
0 = Weak pull-ups are enabled by individual port latch values
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 (CLKOUT)
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
0 = Prescaler is assigned to the Timer0 module
PS2:PS0: Prescaler Rate Select bits
