37 Status Reporting
• To monitor an event, first clear the event; then, enable the event. All of
the events are cleared when you initialize the instrument.
• To allow a service request (SRQ) interrupt to an external controller,
enable at least one bit in the Status Byte Register (by setting, or
unmasking, the bit in the Service Request Enable register).
The Status Byte Register, the Standard Event Status Register group, and
the Output Queue are defined as the Standard Status Data Structure
Model in IEEE 488.2- 1987.
The bits in the status byte act as summary bits for the data structures
residing behind them. In the case of queues, the summary bit is set if the
queue is not empty. For registers, the summary bit is set if any enabled
bit in the event register is set. The events are enabled with the
corresponding event enable register. Events captured by an event register
remain set until the register is read or cleared. Registers are read with
their associated commands. The *CLS command clears all event registers
and all queues except the output queue. If you send *CLS immediately
after a program message terminator, the output queue is also cleared.
