Lite timer 2 (LT2)

10.3.1

Introduction

The Lite timer can be used for general-purpose timing functions. It is based on two free-

running 8-bit upcounters, a watchdog function and an 8-bit Input Capture register.

10.3.2

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

●

Watchdog

– Enabled by hardware or software (configurable by option byte)

– Optional reset on HALT instruction (configurable by option byte)

– Automatically resets the device unless disable bit is refreshed

– Software reset (Forced Watchdog reset)

– Watchdog reset status flag
