TJA1043: Did it can be wake up by wakeup pin, but not the CAN frame? that means, we need the IC wakeup only by wakeup pin, and the CAN frame not available.thanks

Hi shuang

The CAN controller can able to read back its own sent messages even though the bus line is open.

Hence, there won't be a chance of transmit error count, only the receive error count will get increased due to no acknowledgement. So, "Bus Off" will not happen when CANH or CANL is disconnected from the network.

Sorry, I didn't understand. What I want to know is, if only the wakeup pin available, but the CAN message wake up not available for the TJA1043? thanks
