3 Status Registers
Standard Event Status Register
28
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 at the beginning of
Reference" on page 51 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.
See "Setting and Querying the Status Register"
for more information.
