Meaning and Type

*CLS

Meaning and Type

Clear Status Device Status

Description

This command causes the following actions (see "Chapter 4 - Status Reporting" for descriptions of all registers):

•Clears the following registers:

•Standard Event Status.

•Operation Status Event.

•Questionable Status Event.

•Status Byte.

•Clears the Error Queue.

•If *CLS immediately follows a program message terminator (<NL>), then the output queue and the MAV bit are also cleared.

Command Syntax	*CLS
Parameters	(None)
Query Syntax	(None)

*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.

Bit Configuration of Standard Event Status Enable Register

Bit Position	7	6	5	4	3	2	1	0
Bit Name	PON	0	CME	EXE	DDE	QYE	0	OPC
Bit Weight	128	64	32	16	8	4	2	1

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 Supplemental Characteristics in Chapter 1 of the power supply Operating Guide). Programs that repeatedly cause write cycles to non- volatile memory can eventually exceed the maximum number of write cycles and may cause the memory to fail.
