REMOTE CONTROL: COMMON COMMAND SET

Page 67
Function: Sets the Service Request Enable Register (SRER). An integer value
indicates which service is enabled, with the following bit map:
Bits 7 to 0 have values of 128, 64, 32, 16, 8, 4, 2 and 1, respectively.
For example, if bits 4 and 5 are set then the integer value is 48 (16+32).
Note that if both MAV and ESB are disabled, then the bits MSS and
RQS and the line SRQ are never going to be raised (see section 9.1 for
more details).
On power-on, this register is cleared if the Power-on Status Clear bit is
1, or restored if the bit is 0 (see *PSC for more details).
*SRE? Service Request Enable Query
Type: Status command
Function: An integer value representing the value of the Service Request Enable
Register is placed in the output queue. The possible values are listed in
the *SRE command section.
*STB? Status Byte Query
Type: Status command
Function: The value of the Status Byte Register is put into the output queue. Con-
trary to the “*ESR?” command, this register is not cleared by reading it.
The register will be zero only when all its related structures are cleared,
namely the Event Status Register (ESR) and the output queue.

1 = enable Message Available bit (MAV)
