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.
Notes 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.
