DESE
Description
This command sets and queries the bits in the Device Event Status En-
able Register (DESER). The DESER is the mask that determines
whether events are reported to the Standard Event Status Register
(SESR), and entered into the Event Queue. For a more detailed discus-
sion of the use of these registers, see Registers.

Syntax 1
DESE <NR1>
Syntax 2
DESE?
Argument
H <NR1>
The binary bits of the DESER are set according to this value, which
ranges from 1 through 255. For example, DESE 209 sets the DESER
to the binary value 11010001 (that is, the most significant bit in the
register is set to 1, the next most significant bit to 1, the next bit to 0,
etc.).
The power--on default for DESER is all bits set if *PSC is 1. If *PSC
is 0, the DESER maintains the previous power cycle value through
the current power cycle.
Note: Setting the DESER and ESER to the same value allows only
those codes to be entered into the Event Queue and summarized on
the ESB bit (bit 5) of the Status Byte Register. Use the *ESE com-
mand to set the ESER.
Example 1
DESE 209
This sets the DESER to binary 11010001, which enables the PON,
URQ, EXE and OPC bits.
Example 2
DESE?
This query might return :DESE 186, showing that the DESER con-
tains the binary value 10111010.
