2.2 RAS Function - Details
Alarm Monitoring
This feature alternately writes Time Up Count values from the CPU to the RAS feature’s special
programmable timer and then periodically clears them, which provides a means of monitoring the
CPU’s performance. If the clearing of this count value is stopped, the timer will overflow and an
alarm will be detected. The System Monitor utility can be used to enable or disable this feature, as
well as designate what type of processing is to be performed.
