Service Request Enable Register#

 

C0074

#Bit 6 in this register ignores data sent by *SRE and always returns 0 in response to *SRE?

<erb>

is a device defined queue summary bit indicating that the error queue is

 

non-empty.

<rqs>

is set by a request for service and is cleared by the poll.

<esb>

is the standard event register summary bit.

<mav>

is 'message available' indicating that the output queue is non-empty.

<hsb>

is 'hardware status' summary bit

<csb>

is 'coupling status' summary bit

<ssb>

is 'instrument status' summary bit

<rqs>, <esb> and <mav> are defined in IEEE 488.2

<rqs> (request for service) will produce an SRQ at the controller. It is set by a change to either the Status Byte or the Service Enable Register that results in a New Reason for Service. It is cleared when <mss> goes FALSE (i.e. no reason for service) or by Serial Poll.
