28.1.1 Free-Running Period Mode
The value of T2TMR is compared to that of the period register, T2PR,
on each clock cycle. When the two values match, the comparator resets the value of T2TMR to
0x00
on the next cycle and increments the output postscaler counter.
When the postscaler count equals the value in the OUTPS
bits of the T2CON register then a one clock period wide pulse occurs on the TMR2_postscaled
output, and the postscaler count is cleared.
