13.0
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
• Software programmable postscaler
• Interrupt on TMR2 to PR2 match
• Optional use as the shift clock for the
The module is controlled through the T2CON register
(Register 13-1) which enables or disables the timer 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
Figure 13-1.

13.1
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 con-
trol 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
Section 13.2 “Timer2 Interrupt”).
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.
