Status Reporting

Event Status Register

Event Status Register

The Event Status Register is an IEEE 488.2 defined register. The bits in this register are "latched." That is, once an event happens which sets a bit, that bit will only be cleared if the register is read.

Service Request Enable Register

The Service Request Enable Register is an 8-bit register. Each bit enables the corresponding bit in the status byte to cause a service request. The sixth bit does not logically exist and is always returned as a zero. To read and write to this register, use the *SRE? and *SRE commands.

Bit Definitions

The following mnemonics are used in figure 7-1 and in chapter 9, "Common Commands:"

MAV - message available

Indicates whether there is a response in the output queue.

ESB - event status bit

Indicates if any of the conditions in the Standard Event Status Register are set and enabled.

MSS - master summary status

Indicates whether the device has a reason for requesting service. This bit is returned for the *STB? query.

RQS - request service

Indicates if the device is requesting service. This bit is returned during a serial poll. RQS will be set to 0 after being read via a serial poll (MSS is not reset by *STB?).
