14.0
The Timer2 timer module incorporates the following
features:
• 8-bit Timer and Period registers (TMR2 and PR2,
• Readable and writable (both registers)
• Software-programmable prescaler (1:1, 1:4 and
• Software-programmable postscaler (1:1 through
• Interrupt on TMR2-to-PR2 match
• Optional use as the shift clock for the MSSP
The module is controlled through the T2CON register
(Register
and configures the prescaler and postscaler. Timer2
can be shut off by clearing control bit, TMR2ON
(T2CON<2>), to minimize power consumption.
A simplified block diagram of the module is shown in

In normal operation, TMR2 is incremented from 00h on
each clock (F
clock input gives direct input, divide-by-4 and divide-by-16
prescale options; these are selected by the prescaler
control bits, T2CKPS<1:0> (T2CON<1:0>). 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 the next cycle and drives the output counter/
postscaler (see
The TMR2 and PR2 registers are both directly readable
and writable. The TMR2 register is cleared on any
device Reset, while the PR2 register initializes at 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
• any device Reset (Power-on Reset, MCLR Reset,
TMR2 is not cleared when T2CON is written.
