18.1
The clock input to the Timer2 module is the system
instruction clock (F
TMR2 increments from 00h on each clock edge.
A 4-bit counter/prescaler on the clock input allows direct
input, divide-by-4 and divide-by-16 prescale options.
These options are selected by the prescaler control bits,
T2CKPS<1:0> of the T2CON register. The value of
TMR2 is compared to that of the Period register, PR2, on
each clock cycle. When the two values match, the
comparator generates a match signal as the timer
output. This signal also resets the value of TMR2 to 00h
on
counter/postscaler
Interrupt”).
The TMR2 and PR2 registers are both directly readable
and writable. The TMR2 register is cleared on any
device Reset, whereas the PR2 register initializes to
FFh. Both the prescaler and postscaler counters are
cleared on the following events:
• a write to the TMR2 register
• a write to the T2CON register
• Power-on Reset (POR)
• Brown-out Reset (BOR)
• MCLR Reset
• Watchdog Timer (WDT) Reset
• Stack Overflow Reset
• Stack Underflow Reset
• RESET Instruction
18.2
Timer2 can also generate an optional device interrupt.
The Timer2 output signal (TMR2-to-PR2 match)
provides the input for the 4-bit counter/postscaler. This
counter generates the TMR2 match interrupt flag which
is latched in TMR2IF of the PIR1 register. The interrupt
is enabled by setting the TMR2 Match Interrupt Enable
bit, TMR2IE of the PIE1 register.
A range of 16 postscale options (from 1:1 through 1:16
inclusive) can be selected with the postscaler control
bits, T2OUTPS<3:0>, of the T2CON register.

The unscaled output of TMR2 is available primarily to
the PWMx module, where it is used as a time base for
operation.

Timer2 cannot be operated while the processor is in
Sleep mode. The contents of the TMR2 and PR2
registers will remain unchanged while the processor is
in Sleep mode.
