OPTION Register
The OPTION register is a readable and writable
register,
which
contains
various
control
bits
to
configure:
TMR0/WDT prescaler
External GP2/INT interrupt
TMR0
Weak pull-ups on GPIO
Note:
To achieve a 1:1 prescaler assignment for
Timer0, assign the prescaler to the WDT
by setting PSA bit of the OPTION register

Legend:
R = Readable bit
W = Writable bit
U = Unimplemented bit, read as ‘0’
-n = Value at POR
‘1’ = Bit is set
‘0’ = Bit is cleared
x = Bit is unknown
bit 7
GPPU: GPIO Pull-up Enable bit
1
= GPIO pull-ups are disabled
0
= GPIO pull-ups are enabled by individual PORT latch values in WPU register
bit 6
INTEDG: Interrupt Edge Select bit
1
= Interrupt on rising edge of INT pin
0
= Interrupt on falling edge of INT pin
bit 5
T0CS: Timer0 Clock Source Select bit
1
= Transition on T0CKI pin
0
= Internal instruction cycle clock (FOSC/4)
bit 4
T0SE: Timer0 Source Edge Select bit
1
= Increment on high-to-low transition on T0CKI pin
0
= Increment on low-to-high transition on T0CKI pin
bit 3
PSA: Prescaler Assignment bit
1
= Prescaler is assigned to the WDT
0
= Prescaler is assigned to the Timer0 module
bit 2-0
PS<2:0>: Prescaler Rate Select bits
Note 1:
A dedicated 16-bit WDT postscaler is available. See Section 12.6 “Watchdog Timer (WDT)” for more
information.
