GPIB (IEEE-488.2) Overview - Status and Event Registers
Status and Event Registers
There are four required status or event registers.
They are:
1) Standard Event Status Enable (ESE) Register
2) Standard Event Status (ESR) Register
3) Service Request Enable (SRE) Register
4) Status Byte (STB).
The following diagram shows how the registers are related to each other. These registers indicate device
status, and allow the programmer to specify which device events will enable a service request.
