*SRE and *SRE?

Parameters

Comments

*STB?

*SRE <unmask> specifies which bits of the Status Byte Register are enabled (unmasked) to generate an IEEE-488.1 service request. Event and summary bits are always set and cleared in the Status Byte Register regardless of the <unmask> value. A "1" in a bit position enables service request generation when the corresponding Status Byte Register bit is set and a “0” disables it. For example, *SRE 16 enables a service request on Message Available bit (bit 4).

unmask is the sum of the decimal weights of the bits to be enabled allowing these bits to pass through to the summary bit RQS (bit 6 in the Status Byte Register). *SRE? returns the current enable <unmask> value.
