6.1
The Timer2 output is also used by the CCP module to
generate the PWM "On-Time", and the PWM period
with a match with PR2.
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 match output of TMR2 goes through a 4-bit
postscaler (which gives a 1:1 to 1:16 scaling) to gener-
ate a TMR2 interrupt (latched in flag bit TMR2IF,
(PIR1<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,
TMR2 is not cleared when T2CON is written.

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 ini-
tialized to FFh upon reset.
6.3
The output of TMR2 (before the postscaler) is fed to the
Synchronous Serial Port module, which optionally uses
it to generate shift clock.
