9.7.1
Overview
The asynchronous event counter is incremented by external event clock input.
1. Features
Features of the asynchronous event counter are given below.
• Can count asynchronous events
Can count external events input asynchronously without regard to the operation of base clocks ø
and ø
SUB
.
The counter has a 16-bit configuration, enabling it to count up to 65536 (2
16
) events.
•
Can also be used as two independent 8-bit event counter channels.
•
Counter resetting and halting of the count-up function controllable by software
•
Automatic interrupt generation on detection of event counter overflow
•
Use of module standby mode enables this module to be placed in standby mode independently
