STATus Subsystem (Remote Only Commands)
request enable register. This register lets you choose which bits in the status byte register
will trigger a service request.
Send the *SRE <integer> command where <integer> is the sum of the decimal values of
the bits you want to enable plus the decimal value of bit 6. For example, assume that you
want to enable bit 7 so that whenever the standard operation status register summary bit
is set to 1 it will trigger a service request. Send the command *SRE 192 (because 192 = 128
+ 64). You must always add 64 (the numeric value of RQS bit 6) to your numeric sum when
you enable any bits for a service request. The command *SRE? returns the decimal value
of the sum of the bits previously enabled with the *SRE <integer> command.
The service request enable register presets to zeros (0).
