The protocol for the MCU receiving and transmitting messages via the auxiliary signals will be
accomplished with the MSEI and MSEO signal functions respectively. The MSEI signal will provide the
protocol for the MCU receiving messages, and the MSEO signal will provide the protocol for the MCU
transmitting messages.
The MSEI/MSEO protocol is illustrated in
MSEI/MSEO are used to signal the end of variable-length packets and messages. They are not required to
indicate end of fixed length packets. MSEI/MSEO are sampled on the rising edge of MCKI and MCKO
respectively.
Fixed width fields can be concatenated before variable length fields without regard to the individual fields
starting or ending at message N bit boundaries. Variable width fields must end at message N bit boundaries
(where N is MDI/MDO signals).
