... NXP Semiconductors [5] Power-on mode is entered after switching on V 7.2 Sleep mode This mode is the most power-saving mode of the TJA1021. Despite its extreme low current consumption, the TJA1021 can still be woken up remotely via pin LIN, or woken up locally via pin WAKE_N, or activated directly via pin SLP_N. Filters at the inputs of the receiver (LIN), of pin WAKE_N and of pin SLP_N prevent unwanted wake-up events due to automotive transients or EMI ...

... NXP Semiconductors integrated filter to suppress bus line noise. The transmit data stream of the protocol controller at the TXD input is converted by the transmitter into a bus signal with optimized slew rate and wave shaping to minimize EME. The LIN bus output pin is pulled HIGH via an internal slave termination resistor ...

... NXP Semiconductors has been added, a HIGH level indicates a remote wake-up request (weak pull-down at pin TXD) and a LOW level indicates a local wake-up request (strong pull-down at pin TXD; much stronger than the external pull-up resistor). The wake-up request flag (signalled on pin RXD) as well as the wake-up source flag (signalled on pin TXD) are reset immediately after the microcontroller sets pin SLP_N HIGH ...
