The Timer0 module timer/counter has the following
features:
• 8-bit timer/counter
• Readable and writable
• 8-bit software programmable prescaler
• Internal or external clock select
• Interrupt on overflow from FFh to 00h
• Edge select for external clock
Figure 4-1 is a block diagram of the Timer0 module and
the prescaler shared with the WDT.
4.1
Timer mode is selected by clearing the T0CS bit
(OPTION_REG<5>). In Timer mode, the Timer0
module will increment every instruction cycle (without
prescaler). If TMR0 is written, the increment is inhibited
for the following two instruction cycles. The user can
work around this by writing an adjusted value to the
TMR0 register.

Counter mode is selected by setting the T0CS bit
(OPTION_REG<5>). In this mode, the Timer0 module
will increment either on every rising or falling edge of
pin GP2/T0CKI. The incrementing edge is determined
by
(OPTION_REG<4>). Clearing the T0SE bit selects the
rising edge.
4.2
A Timer0 interrupt is generated when the TMR0
register timer/counter overflows from FFh to 00h. This
overflow sets the T0IF bit. The interrupt can be masked
by
(INTCON<2>) must be cleared in software by the
Timer0 module Interrupt Service Routine before re-
enabling this interrupt. The Timer0 interrupt cannot
wake the processor from Sleep since the timer is shut-
off during Sleep.
Note:

Counter mode has specific external clock
requirements. Additional information on
these requirements is available in the PIC
