CRC Errors/NACK Response
SAB Address Mode
The Service Access Bus uses 36 address bits to address memory or registers in any of the
slaves on the bus. The bus supports sized accesses of bytes (8 bits), halfwords (16 bits), or
words (32 bits). All accesses must be aligned to the size of the access, i.e. halfword accesses
must have the lowest address bit cleared, and word accesses must have the two lowest address
bits cleared.
Two instructions exist to access the SAB: MEMORY_WRITE and MEMORY_READ. These two
instructions write and read words, halfwords, and bytes from the SAB.
Busy Reporting
If the aWire master, during a MEMORY_WRITE or a MEMORY_READ command, transmit
another byte when the aWire is still busy sending the previous byte to the SAB, the AW will
respond with a MEMORY_READ_WRITE_STATUS error. See chapter
more details.
The aWire master should adjust its baudrate or delay between bytes when doing SAB accesses
to ensure that the SAB is not overwhelmed with data.
Error Reporting
If a write is performed on a non-existing memory location the SAB interface will respond with an
error. If this happens, all further writes in this command will not be performed and the error and
number of bytes written is reported in the MEMORY_READWRITE_STATUS message from the
AW after the write.
If a read is performed on a non-existing memory location, the SAB interface will respond with an
error. If this happens, the data bytes read after this event are not valid. The AW will include three
extra bytes at the end of the transfer to indicate if the transfer was successful, or in the case of
an error, how many valid bytes were received.
The AW will calculate a CRC value when receiving the command, length, and data fields of the
command packets. If this value differs from the value from the CRC field of the packet, the AW
will reply with a NACK response. Otherwise the command is carried out normally.
An unknown command will be replied with a NACK response.
In worst case a transmission error can happen in the length or command field of the packet. This
can lead to the aWire slave trying to receive a command with or without length (opposite of what
the master intended) or receive an incorrect number of bytes. The aWire slave will then either
wait for more data when the master has finished or already have transmitted the NACK
response in congestion with the master. The master can implement a timeout on every com-
mand and reset the slave if no response is returned after the timeout period has ended.
