4.5.5 Read and Set Service Request Enable Register

This command sets the Service Request Enable Register (SRE). This register, defined in Table

4.8, determines which bits from the Status Byte Register (see *STB for its bit configuration) are

allowed to set the Master Status Summary (MSS) Bit. A 1 in any SRE bit position enables the

corresponding Status Byte Register bit. All Status Byte Register enabled bits are then logically

OR’d and placed in bit 6 of the Status Byte Register. When *SRE is cleared (by programming it

with 0), the power supply cannot generate a service request to the controller.

Command Syntax: *SRE <NR1>

Example: *SRE 20

Query Syntax: *SRE?

Return Parameter: <NR1> (Register value)

Related Commands: *ESE, *ESR
