Introduction
Timer2 is an 8-bit timer with a prescaler, a postscaler, and a period register. Using the prescaler
and postscaler at their maximum settings, the overflow time is the same as a 16-bit timer.
Timer2 is the PWM time-base when the CCP module(s) is used in the PWM mode.
Figure 13-1
the TMR2 register matched the PR2 register. This can be useful in reducing the overhead of the
interrupt service routine on the CPU performance.

shows a block diagram of Timer2. The postscaler counts the number of times that
TMR2 register output can be software selected by the SSP Module as a baud clock.
