The Status Byte Register
The Status Byte register consolidates the status
events of all the status registers. The Status Byte
register can be read with the *STB? query or a
serial poll and can be cleared with the *CLS
command.
Clearing the events in any of the status registers
will clear the corresponding bit in the Status Byte
register.
The Status byte enable register is cleared when the
*SRE 0 command is used.
The Status Byte Condition register is cleared when
the *CLS command is used.
