Standard Event Status Register

32
The standard event status register is used to determine the specific
event that sets bit 5 in the status byte register. The standard event
status register does not have negative and positive transition
registers, nor a condition register. Use the IEEE common
commands to access the register.
To query the standard event status register, send the *ESR
command. The response will be the decimal sum of the bits which
are set to 1. For example, if bit number 7 and bit number 3 are set
to 1, the decimal sum of the 2 bits is 128 plus 8. So the decimal
value 136 is returned.
