TJA1145 interrupt on RXD question

[freddy_ben-zeev]

We're considering using TJA1145. The product datasheet says that it uses the RXD signal for interrupt to the MCU. RXD is also the CAN input signal to the MCU. Can such an interrupt happen during normal operation or only in standby and sleep modes? If it can happen in normal operation how do I tell the difference between interrupt and CAN RX data?

Thanks,

Freddy

Hi Freddy,

it can happen only in Standby or Sleep modes, in normal mode RXD has CAN bit stream.
