the bus responds to the poll by sending the contents of its Status Byte Register. If an
instrument on the bus has made a service request, the request service bit (RQS, bit 6) of its
Status Byte Register will be set to 1, identifying it as an instrument that requested service.
The contents of the Status Byte Register (STB) is determined by the Service Request
Enable Register (SRE), Event Status Register (ESR), Event Status Enable Register
(ESE), and the output buffer. These status registers are discussed below and summarized
in Table 5-5. Figure 5-3 shows the relationship of these registers.
