Using Multiprocessor Communication

Use the following procedure to exchange data in Multiprocessor Communication mode (MPCM):

  1. 1.All client MCUs are in Multiprocessor Communication mode.
  2. 2.The host MCU sends an address frame, and all clients receive and read this frame.
  3. 3.Each client MCU determines if it has been selected.
  4. 4.The addressed MCU will disable MPCM and receive all data frames. The other client MCUs will ignore the data frames.
  5. 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.
