12.2
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 output of TMR2 (before the postscaler) is a clock
input to the Synchronous Serial Port module, which
optionally uses it to generate the shift clock.
