11.3 LITE TIMER 2 (LT2)

11.3.1 Introduction

The Lite Timer can be used for general-purpose

timing functions. It is based on two free-running 8-

bit upcounters, an 8-bit input capture register.

11.3.2 Main Features

Realtime Clock

– One 8-bit upcounter 1 ms or 2 ms timebase

period (@ 8 MHz fOSC)

– One 8-bit upcounter with autoreload and pro-

grammable timebase period from 4µs to

1.024ms in 4µs increments (@ 8 MHz fOSC)

– 2 Maskable timebase interrupts

Input Capture

– 8-bit input capture register (LTICR)

– Maskable interrupt with wakeup from Halt

Mode capability
