Locking the counter does not work. The device will not error until the cycle is started. The device must be confirming that it can decrement the counter before it proceeds.

It is possible to lock any field on the SRI/SRT512 devices. Is it possible to lock the counter and have the device not error out?
Need to run:
The contents will be displayed in the format
12345678
and to write the format78563412
must be used. The counters are in addresses 5 and 6 and the corresponding register bits 21 and 22. Writingxxxx9Fxx
will lock them.
