IEEE 488.2 Register Model
6.5 The Status Byte Register
The Status Byte register reports conditions from the other registers. Data in the
instruments output buffer is immediately reported on the “Message Available”
bit (bit 4). Clearing an event register from one of the other registers will clear
the corresponding bits in the Status Byte condition register. Reading all
messages from the output buffer, including any pending queries, will clear the
“Message Available” bit. To set the enable register mask and generate an SRQ
(service request), you must write a decimal value to the register using the *SRE
command.
