*ESE
Meaning and Type
Event Status Enable Device Status
Description
This command programs the Standard Event Status Enable register bits. The programming determines which events of the
Standard Event Status Event register (see *ESR?) are allowed to set the ESB (Event Summary Bit) of the Status Byte
register. A "1" in the bit position enables the corresponding event. All of the enabled events of the Standard Event Status
Event register are logically ORed to cause the Event Summary Bit (ESB) of the Status Byte register to be set. See "Chapter
4 - Status Reporting" for descriptions of all three registers.

CME = Command error; DDE = Device-dependent error; EXE = Execution error;
OPC = Operation complete; PON Power-on; QYE = Query error.
Command Syntax *ESE <NRf>
Parameters 0 to 255
Power On Value (See *PSC)
Suffix (None)
Example *ESE 129
Query Syntax *ESE?
Returned Parameters <NR1> (Register value)
Related Commands *ESR? *PSC *STB?
If PSC is programmed to 0, then the *ESE command causes a write cycle to nonvolatile memory. The
nonvolatile memory has a finite maximum number of write cycles (see Table A-2, Supplementary
Characteristics). Programs that repeatedly cause write cycles to nonvolatile memory
can eventually exceed the maximum number of write cycles and may cause the memory to fail.
*ESR?
Meaning and Type
Event Status Register Device Status
Description
This query reads the Standard Event Status Event register. Reading the register clears it. The bit configuration of this
register is the same as the Standard Event Status Enable register (*ESE). See "Chapter 8 - Status Reporting" for a detailed
explanation of this register.
Query Syntax *ESR?
Parameters (None)
Returned Parameters <NR1> (Register binary value)
