addresses or SCI configuration register addresses. Because of the address space of the
OctalFALC
MSBs are ignored.
The Frame Check Sequence FCS has16 bits.
The Read Status Byte RSTA of the acknowledge message shows the status of the
received message and is built by the SCI interface of the OctalFALC
and
The destination address in the ACK message is always the source address of the
corresponding CMD (the address of the microcontroller), see
CMD messages will be sent by the OctalFALC
