MCU M4 controller CAN & I2C questions

Hi,

MCU Controller

  1. In cases where there are only 2 nodes on the bus and only 1 of them is in Active mode, will the node in Listen-Only-Mode be able to receive a message?
  2. Is the I2C controller able to detect and generate an interrupt on stop signal?
Thanks.
Best Regards
Sky Lee

    Sky,

    1. Is this first question about CAN? If so, there is a Silent Mode available where you can suppress the transmission of ACKs and error frames.
    2. The I2C module in slave mode can generate interrupts on the stop signal.

    Sections 17.3.13.1 and 16.3.3.2 of this datasheet will have more information.
