Timer5 combines two 8-bit registers to function as a
16-bit timer. The TMR5L register is the actual low byte
of the timer; it can be read and written to directly. The
high byte is contained in an unmapped register; it is
read and written to through TMR5H, which serves as
a buffer. Each register increments from 00h to FFh.
A second register pair, PR5H and PR5L, serves as the
Period register; it sets the maximum count for the
TMR5 register pair. When TMR5 reaches the value of
PR5, the timer rolls over to 00h and sets the TMR5IF
interrupt flag. A simplified block diagram of the Timer5
module is shown in Figure 2-1.

Timer5 supports three configurations:
• 16-Bit Synchronous Timer
• 16-Bit Synchronous Counter
• 16-Bit Asynchronous Counter
In Synchronous Timer configuration, the timer is
clocked by the internal device clock. The optional
Timer5 prescaler divides the input by 2, 4, 8 or not at all
(1:1). The TMR5 register pair increments on Q1.
Clearing TMR5CS (= 0) selects the internal device
clock as the timer sampling clock.
