The OPTION register is a readable and writable regis-
ter which contains various control bits to configure the
TMR0/WDT prescaler, the External INT Interrupt,
TMR0, and the weak pull-ups on GPIO.
OPTION REGISTER
Note:
To achieve a 1:1 prescaler assignment for
the TMR0 register, assign the prescaler to
the Watchdog Timer by setting bit PSA
(OPTION<3>).
