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?<BR /><BR />Thanks,<BR /><BR />Freddy</P></BODY></HTML> Thu, 30 Apr 2020 22:40:16 GMT freddy_ben-zeev 2020-04-30T22:40:16Z TJA1145 interrupt on RXD question https://community.nxp.com/t5/Other-NXP-Products/TJA1145-interrupt-on-RXD-question/m-p/1098257#M9174 <HTML><HEAD></HEAD><BODY><P>We're considering using TJA1145.
