Chapter 13
Timer Module
This chapter describes the configuration and operation of the two general-purpose timer
modules (timer 0 and timer 1). It includes programming examples.
13.1 Overview
The timer module incorporates two independent, general-purpose 16-bit timers, timer 0 and
timer 1. The output of an 8-bit prescaler clocks each timer. There are two sets of registers,
one for each timer. The timers can operate from CLKIN or from an external clocking source
using one of the TIN signals. If CLKIN is selected, it can be divided by 16 or 1.
Figure 13-1 is a block diagram of one of the two identical ti5mer modules.
