Details
The *SRE command is used to program the service request enable register. This command is sent
with the decimal equivalent of the binary value that determines the desired state (0 or 1) of each bit in
the register. This register is cleared on power-up.
This enable register is used along with the status byte register to generate service requests (SRQ).
With a bit in the service request enable register set, an SRQ occurs when the corresponding bit in the
status byte register is set by an appropriate event. For details on register structure, refer to Status
structure (on page 13-1).
