PIC Timer 2 calculator
With the PIC Timer 2 calculator you can see the resulting frequencies and
periods when you change four pieces of information. :
- Frequency (the default is 4MHz).
- The Prescaler ratio.
- Timer 2
period register value.
- The Postscaler ratio.

PICTimer 2 registers [from 33023a.pdf]
Three
sliders let you change the values by dragging a control up and down on the
screen and the resulting changes are immediately shown in this page. The
first is for the prescaler, the middle is for the Period register and the
last is for the postscaler.
Note: Setting of timer 2 value is not shown
as the intended use of the timer is for making it easy to control the period of
TMR2 using the period register - taking away the need to service interrupts in
order to generate a specific frequency.
All you do is set the Prescaler and Postscaler and set the period register PR2.
For example if you set Prescaler=1:1 and Postscaler=1:1 and PR2=99. The
output period of the module would be 100us i.e. a Timer 2 interrupt every
100us.
Note: Timer 2 counter is reset on the next count after matching PR2 (this is why
you need PR2=99 and not 100).
The important point is that there will be no need to set any registers within
the interrupt (as you have to do with the other timers). This is why it is
used as the baud rate generator for the USARTs - it requires no processing.
