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

●

Real-time clock

–

One 8-bit upcounter 1 ms or 2 ms timebase period (@ 8 MHz fOSC)

–

One 8-bit upcounter with autoreload and programmable timebase period from 4µs

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

–

2 Maskable timebase interrupts.

●

Input capture

–

8-bit input capture register (LTICR)

–

Maskable interrupt with wakeup from HALT mode capability.
