STATUS REGISTERS
139
MSS &

The Master Summary Status is used with
the *STB? query. When the *STB? query
is read the MSS bit is not cleared. The
Request Service bit is cleared when it is
polled during a serial poll.
Service Request Register
Description
The Service Request Generation Register
determines which events in the Status Byte
Register will generate Service Requests. It is
essentially the Status Byte Enable Register. The bit
events are the same as the Status Byte Register,
minus the MSS/RQS bit.
