Status Subsystem Overview
Standard Event Status Register Model
Summary Message Bit The Summary Message is a single-bit message which indicates whether or not one
or more of the enabled events have occurred since the last reading or clearing of the Event Register. The test
set logically ANDs corresponding bits in the Event and Enable registers and then performs an inclusive OR on
all the resulting bits to generate the Summary Message. By use of the enable bits, the application program can
direct the test set to set the Summary Message to the 1, or TRUE, state for a single event or an inclusive OR of
any group of events.
The Summary Message is TRUE, logic 1, if the register contains some information and an enabled event in the
Event Register is set TRUE.
The Summary Message is FALSE, logic 0, if the queue is empty and no enabled events are TRUE. Registers
can be cleared by reading all the information from the queue. Registers can also be cleared using the *CLS
(clear status) command.
