PIC18F6525/6621/8525/8621
13.2
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.

Note 1: TMR2 register output can be software selected by the MSSP module as a baud clock.
x = unknown, u = unchanged, — = unimplemented, read as ‘0’. Shaded cells are not used by the Timer2 module.
Enabled only in Microcontroller mode for PIC18F8525/8621 devices.
