Service Request Enable Register
In addition to the status byte register, the status byte group als o
contains the service request enable register . The status byte service
request enable register lets you choose which bits in the Status Byt e
Register will trigger a service request .
Send the
*SRE <number>
command (where
<number>
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 tha t
whenever the operation status summary bit is set to 1, it will trigger a
service request . Send the *SRE 192 (128 + 64) command . The
*SRE ?
command returns the decimal value of the sum of the bits enable d
previously with the
*SEE <number>
command .
NOTE
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 service request enable register contains the following bits:
