11.0
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 11-1 is a block diagram of the Timer0 module.
11.1
The Timer0 module can be used as either an 8-bit timer
or an 8-bit counter.
11.1.1
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
register.

When TMR0 is written, the increment is inhibited for
two instruction cycles immediately following the write.
11.1.2
In 8-Bit Counter mode, the Timer0 module will
increment on every rising or falling edge of the T0CKI
pin or the Capacitive Sensing Oscillator (CPSOSC)
signal.
8-Bit Counter mode using the T0CKI pin is selected by
setting the T0CS bit in the OPTION register to ‘1’ and
resetting the T0XCS bit in the CPSCON0 register to ‘0’.
8-Bit Counter Mode using the Capacitive Sensing
Oscillator (CPSOSC) signal is selected by setting the
T0CS bit in the OPTION register to ‘1’ and setting the
T0XCS bit in the CPSCON0 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 register.
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.
