1/10thsec clock pulse

how do I create a 1/10thsec clock pulse, if any one could tell me that would be great.

Im using Syswin

The least signficant bit of the accumulated time of a timer with a .01 time base will pulse on for .01 seconds, then off for .01 seconds. Look at the binary value:

0 s = 0000
.1 s = 0001
.2 s = 0010
.3 s = 0011
.4 s = 0100
.5 s = 0101
.6 s = 0110
.7 s = 0111

Notice how the least signifcant bit, ie, the bit at the end, is alterenating on and off each time the timer upticks. Create a timer that self resets on any EVEN time period, say 60 seconds - use an even number to avoid getting a spurious single scan pulse that you would get because odd numbers have the least significant bit set. Then use the least significnat bit of the elapsed time for your 1/10th second pulse.

Note that a full on/off cycle takes .2 seconds.

If you require a single shot pulse that occurs once each .1 seconds then use the DIFU and DIFD instructions on the elapsed time least signifcant bit to get a one scan long pulse every .1 seconds.
