14.4.2 *ESE
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
Enable Register are logically ORed to cause the Event Summary Bit (ESB) of the Status Byte
Register to be set. See Chapter 16 for descriptions of the Standard Event Status registers.
The query reads the Standard Event Status Enable register.
