Use the following procedure to exchange
data in Multiprocessor Communication mode (MPCM):
- 1.All client MCUs are in Multiprocessor
Communication mode.
- 2.The host MCU sends an address frame,
and all clients receive and read this frame.
- 3.Each client MCU determines if it has
been selected.
- 4.The addressed MCU will disable MPCM
and receive all data frames. The other client MCUs will ignore the data frames.
- 5.When the addressed MCU has received
the last data frame, it must enable MPCM again and wait for a new address frame from the
host.
The process then repeats from step 2.
