8.0
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
T2CKPS1:T2CKPS0 (T2CON<1:0>).
The Timer2 module has an 8-bit Period Register PR2.
Timer2 increments from 00h until it matches PR2 and
then resets to 00h on the next increment cycle. PR2 is
a readable and writable register. The PR2 register is
initialized to FFh upon RESET.
The match output of TMR2 goes through a 4-bit
postscaler (which gives a 1:1 to 1:16 scaling inclusive)
to generate a TMR2 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.

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
TMR2 is not cleared when T2CON is written.
8.2
The output of TMR2 (before the postscaler) is fed to the
Synchronous Serial Port module which optionally uses
it to generate shift clock.
