4.2.2.2
OPTION Register
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.
REGISTER 4-2:
OPTION REGISTER (ADDRESS: 81h, 181h)
Note:
To achieve a 1:1 prescaler assignment for
TMR0, assign the prescaler to the WDT
(PSA = 1). See Section 6.3.1.
