12.0 TIMER0 MODULE
The Timer0 module is an 8-bit timer/counter with the
following features:
8-bit timer/counter register (TMR0)
8-bit prescaler (shared with Watchdog Timer)
Programmable internal or external clock source
Programmable external clock edge selection
Interrupt on overflow
TMR0 can be used to gate Timer1
Figure 12-1 is a block diagram of the Timer0 module.
12.1
Timer0 Operation
The Timer0 module can be used as either an 8-bit timer
or an 8-bit counter.
12.1.1
8-BIT TIMER MODE
The Timer0 module will increment every instruction
cycle, if used without a prescaler. 8-Bit Timer mode is
selected by clearing the T0CS bit of the OPTION_REG
register.
When TMR0 is written, the increment is inhibited for
two instruction cycles immediately following the write.
12.1.2
8-BIT COUNTER MODE
In 8-Bit Counter mode, the Timer0 module will increment
on every rising or falling edge of the T0CKI pin.
8-Bit Counter mode using the T0CKI pin is selected by
setting the T0CS bit in the OPTION_REG register to ‘1’.
The rising or falling transition of the incrementing edge
for either input source is determined by the T0SE bit in
the OPTION_REG register.

BLOCK DIAGRAM OF THE TIMER0/WDT PRESCALER
Note:
The value written to the TMR0 register
can be adjusted, in order to account for
the two instruction cycle delay when
TMR0 is written.
