Enable Registers
DESER, ESER, and SRER allow you to select which events are reported to the
Status Registers and the Event Queue. Each Enable Register acts as a
fi
lter to a
Status Register (the DESER also acts as a
fi
lter to the Event Queue) and can
prevent information from being recorded in the register or queue.
Each bit in an Enable Register corresponds to a bit in the Status Register it
controls. In order for an event to be reported to a bit in the Status Register, the
corresponding bit in the Enable Register must be set to one. If the bit in the Enable
Register is set to zero, the event is not recorded.
Various commands set the bits in the Enable Registers. The Enable Registers and
the commands used to set them are described below.
The Device Event Status Enable Register (DESER).
This register controls which
types of events are reported to the SESR and the Event Queue. The bits in the
DESER correspond to those in the SESR.
Use the DESE command to enable and disable the bits in the DESER. Use the
DESE? query to read the DESER.
Figure 3-3: The Device Event Status Enable Register (DESER)
The Event Status Enable Register (ESER).
This register controls which types of
events are summarized by the Event Status Bit (ESB) in the SBR. Use the *ESE
command to set the bits in the ESER. Use the *ESE? query to read it.
Figure 3-4: The Event Status Enable Register (ESER)
The Service Request Enable Register (SRER).
This register controls which bits
in the SBR generate a Service Request and are summarized by the Master Status
Summary (MSS) bit.
