The status is 0x00 and all data read are valid. An unsuccessful four byte read can look like this:
The error occurred after reading 2 bytes on the SAB. The rest of the bytes read are undefined.
The status byte indicates the error and the bytes remaining indicates how many bytes were
remaining to be sent of the data field of the packet when the error occurred.
