6.C.14 Recall Service Request Enable
This Status Byte data structure conforms to the IEEE 488.2 standard requirements for this structure.
SRE?
recalls the enable mask for the standard defined events. Refer
to Section 6, Subsection 6.5.
Response Decode:
The value returned, when converted to base 2 (binary), identifies
the enabled bits which will generate a service request. The detail
is contained in the IEEE 488.2 standard document.
6.C.15 Read Service Request Register
This Status Byte data structure conforms to the IEEE 488.2 standard requirements for this structure.
STB?
recalls the service request register for summary bits. Refer to
Section 6, Subsection 6.5.
Response Decode:
The value returned, when converted to base 2 (binary), identifies
the summary bits for the current status of the data structures
involved. For the detail definition see the IEEE 488.2 standard
document. There is no method of clearing this byte directly. Its
condition relies on the clearing of the overlying status data
structure.

* SRE?
Execution Errors:
None.
Power On and Reset Conditions
The Power On condition depends on the condition stored by the
common PSC command - if 0 then it is not cleared; if 1 then the
register is cleared. Reset has no effect.
