Timer2 is an 8-bit timer with a prescaler and a
postscaler. It can be used as the PWM time base for
PWM mode of the CCP module. The TMR2 register is
readable and writable, and is cleared on any device
Reset.
The input clock (F
1:4 or 1:16, selected by control bits T2CKPS<1:0>
(T2CON<1:0>).
The Timer2 module has an 8-bit period register PR2.
The TMR2 register value increments from 00h until it
matches the PR2 register value and then resets to 00h
on the next increment cycle. The PR2 register is a
readable and writable register. The PR2 register is
initialized to FFh upon Reset.
The match output of Timer2 goes through a 4-bit
postscaler (which gives a 1:1 to 1:16 scaling inclusive)
to generate a Timer2 interrupt (latched in flag bit
TMR2IF, (PIR1<1>)).
Timer2 can be shut off by clearing control bit TMR2ON
(T2CON<2>) to minimize power consumption.
Register 8-1 shows the Timer2 control register.

8.1
The prescaler and postscaler counters are cleared
when any of the following occurs:
• a write to the TMR2 register
• a write to the T2CON register
• any device Reset (Power-on Reset, MCLR Reset,
The TMR2 register is not cleared when T2CON is
written.
8.2
The TMR2 output (before the postscaler) is fed to the
Synchronous Serial Port module which optionally uses
it to generate shift clock.
