    Status Byte Register The Status Byte summary register reports conditions from the other status registers. Query data that is waiting in the U2722A/U2723A's output buffer is immediately reported via message available bit (bit 4). Bits in the summary register are not latched. Clearing an event register will clear the corresponding bits in the Status Byte summary register.
