disable the emergency stop function and clear EMG_SHDN sta-
tus.

“1” means the function is enable and “0” menas that is disable.
When Emergency Shutdown’s Input Pin (from the terminal con-
nector) is one shot high, it will force PCI7260 enter the state of
“SHDN”( Relay Output pattern is determined on EMG_SHDN Dip
Swith(S3)). Whenever the users wants to control the relay output
by “Relay Output Control Register”, the relay pattern won’t
change until users acess the “EMG_SHDN Recovery bit”.
