... NXP Semiconductors Table 4. Failure [1] A weak termination implies a pull-down current source behavior typical. [2] A weak termination implies a pull-up current source behavior typical. Failure 6 is detected if the CANL bus line exceeds its comparator threshold for a certain period of time. This delay is needed to avoid false triggering by external RF fields. After detection of failure 6, the reception is switched to the single-wire mode through CANH ...

... NXP Semiconductors A local wake-up through pin WAKE is detected by a rising or falling edge with a consecutive level exceeding the maximum specifi wake-up request the transceiver will set the output on pin INH to HIGH which can be used to activate the external supply voltage regulator. A wake-up request is signalled on ERR or RXD with an active LOW signal. So the external microcontroller can activate the transceiver (switch to normal operating mode) via pins STB and EN ...
