A.10 *SRE — SERVICE REQUEST ENABLE COMMAND
*SRE
Syntax:
*SRE
grammed.
Description: Sets the condition of the Service Request Enable register. The Service Request Enable register
determines which events of the Status Byte Register are summed into the MSS (Master Status Sum-
mary) and RQS (Request for Service) bits. RQS is the service request bit that is cleared by a serial
poll, while MSS is not cleared when read. A “1” (1 = set = enable, 0 = reset = disable) in any Service
Request Enable register bit position enables the corresponding Status Byte bit to set the RQS and
MSS bits. All the enabled Service Request Enable register bits then are logically ORed to cause Bit 6
of the Status Byte Register (MSS/RQS) to be set.
