OPTION_REG REGISTER
The OPTION_REG register is a readable and writable
register which contains various control bits to congure
the TMR0 prescaler/WDT postscaler (single assign-
able register known also as the prescaler), the External
INT Interrupt, TMR0, and the weak pull-ups on PORTB.

OPTION_REG REGISTER (ADDRESS 81h)
Note:
To achieve a 1:1 prescaler assignment for
the TMR0 register, assign the prescaler to
the Watchdog Timer.
