SECTION 4 STATUS STRUCTURE
4-13
Reading, writing, and clearing the Extended Event Status Register
Reading
The ESR? common query is used to read the register. The register is cleared after
being read. The response message is integer-format data with the binary weight added
to the event bit and the sum converted to decimal.
Writing With the exception of clearing, data cannot be written to the register from outside.
Clearing
The register is cleared when:
[1] A
∗
CLS command is received
[2] The power is turned on
[3] An event is read for the ESR2? query command
Reading, writing, and clearing the Extended Status Enable Register
Reading
The ESE2? query is used to read the register.
The response message is integer-format data with the binary weight added to the event
bit and the sum converted to decimals.
Writing
The ESE2 program command is used to write the register.
Because bits 0 to 7 of the registers are weighted with values 1, 2, 4, 8, 16, 32, 64, and
128, respectively, the write data is transmitted as integer-format data that is the sum of
the required bit digits selected from the weighted value.
Clearing
The register is cleared when:
[1] An
ESE2 program command with a data value of 0 is received
[2] The power is turned on
The Extended Event Status Enable register is not affected when:
[1] The device clear function status of IEEE488.1 is changed
[2] An
∗
RST common command is received
[3] A
∗
CLS common command is received
