TIMER UNIT

9.1

Overview

A timer is implemented in the CL RC632. It derives its clock from the 13.56 MHz chip-clock. The µ-Processor

may use this timer to manage timing relevant tasks.

The timer unit may be used in one of the following configurations:

•

Timeout-Counter

•

Watch-Dog Counter

•

Stop Watch

•

Programmable One-Shot

•

Periodical Trigger

The timer unit can be used to measure the time interval between two events or to indicate that a specific

event occurred after a specific time. The timer can be triggered by events which will be explained in the

following, but the timer itself does not influence any internal event (e.g. A timeout during data receiving does

not influence the receiving process automatically). Furthermore, several timer related flags are set and these

flags can be used to generate an interrupt.
