8.173 SYSCLEAR (SYSTEM CLEAR RESET manual operation)

8.173.1 Function

The SYSCLEAR command issues a SYSTEM CLEAR RESET manual operation. This is the same as the
“ SYSRESET CLEAR” command. It clears the main storage to x'00'. Additionally the general purpose re-
gisters, control registers, etc. are reset to their initial value. At this point the system is essentially in the
same state as it was just after having been started.

Please note that all CPUs must be stopped prior to issuing a system clear reset or the function will be re-
jected with a message.
