6.1
Timer2 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 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>)).
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
initialized to FFh upon Reset.
