25.3.4.3.1 Using Multiprocessor Communication
The following procedure should be used to exchange data in Multiprocessor Communication mode (MPCM):
- All slave MCUs are in Multiprocessor Communication mode.
- The master MCU sends an address frame, and all slaves receive and read this frame.
- Each slave MCU determines if it has been selected.
- The addressed MCU will disable MPCM and receive all data frames. The other slave MCUs will ignore the data frames.
- When the addressed MCU has received the last data frame, it must enable MPCM again and wait for a new address frame from the master.
The process then repeats from step 2.
