The status registers picture above shows how the different status reporting data
structures work together. To make it possible for any of the Standard Event Status
Register bits to generate a summary bit, the bits must be enabled. These bits are
enabled by using the *ESE common command to set the corresponding bit in the
Standard Event Status Enable Register.
To generate a service request (SRQ) interrupt to an external controller, at least one
bit in the Status Byte Register must be enabled. These bits are enabled by using
the *SRE common command to set the corresponding bit in the Service Request
Enable Register. These enabled bits can then set RQS and MSS (bit 6) in the
Status Byte Register.
