How to wake up the TJA1043 CAN transciever using the CAN Frame? WAKE pin is grounded.
7.2.4 Wake flag
The Wake flag is set when the transceiver detects a local or remote wake-up request. A local wake-up request is detected when the logic level on pin WAKE changes, and the new level remains stable for at least twake. A remote wake-up request is triggered by two bus dominant states of at least twake(busdom), with the first dominant state followed by a recessive state of at least twake(busrec) (provided the complete dominant-recessive-dominant pattern is completed within tto(wake)bus). The Wake flag can be set in Standby mode, Go-to-Sleep mode or Sleep mode. Setting the Wake flag clears the UVNOM flag and timers. Once set, the Wake flag status is immediately available on pins ERR_N and RXD (provided VIO and VBAT are present). This flag is also set at power-on and cleared when the UVNOM flag is set or the transceiver enters Normal mode.
How remote wake up request is triggered?
Thanks in advance!
