The status byte gives the master device information about the slave device’s state, and information about the communication status with the ACK/NACK bit.

The status byte has bits for signaling Status, Warning, Error and Critical error statuses. These bits are cleared when the status word is read. Bits are set when the corresponding status or error state changes in the slave device.
