MEMORY_READWRITE_STATUS
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.
Table 39-51. MEMDATA Status Byte
Table 39-52. MEMDATA Details
After a MEMORY_WRITE command this response is sent by AW. The response can also be
sent after a MEMORY_READ command if AW encountered an error when receiving the
address. The response contains 3 bytes, where the first is the status of the command and the 2
next contains the byte count when the first error occurred. The first byte is encoded this way:
