Programmable Interrupt Timer Modules
(PIT0–PIT3)
23.1
This chapter describes the operation of the four programmable interrupt timer modules,
PIT0–PIT3.
23.1.1 Overview
The PIT is a 16-bit timer that provides precise interrupts at regular intervals with minimal
processor intervention. The timer can either count down from the value written in the modulus
register, or it can be a free-running down-counter.
