Figure 6-7 Event Status Byte Register
6.1.6.4 Event Status Enable Register
The event status enable register (ESE) is a mask determining the conditions in which the ESR
will set bit 5 of the SBR. It is bit-wise ANDed with the ESR and if the result is not zero then
ESB (bit 5) of the SBR is set (see Figure 6-7). Thus any event affecting the ESR can be made to
generate a Service Request in conjunction with the ERE and the SRE.
The event status enable is set by the *ESE command and read by the *ESE? command.
