Workaround implementation
The workaround is to have the last MOb (MOb3) as "spy" enabled all the time; it is the MOb of lowest priority : If a Mob
other than MOb3 is programmed in receive mode and its acceptance filter matches with the incoming message ID, this
Mob will take the message. MOb3 will only take messages than no other MObs will have accepted. MOb3 will need to
be re-enabled fast enough to manage back to back frames. The deadline to do this is the beginning of DLC slot of
incoming frames as explained above.
Minimum code to insert in CAN interrupt routine:
The timer1, when used as a baud rate generator in mode 1 (16 bits counter) for low baud rates, does not generate
baud rate to UART.
Workaround
No
