7.2.4 Reset mode
If a remote wake-up event (see
associated transceiver will switch to Standby mode. A wake-up initiated by the
microcontroller (SLPx_N HIGH for t
Normal mode while the other transceiver remains in its current state.
Standby mode is an intermediate mode between Sleep and Normal modes. A transceiver
will switch from Sleep mode to Standby mode in response to a LIN bus wake-up event.
Pin RXDx will go low to indicate to the microcontroller the source of the remote wake-up
(LIN1 or LIN2). A transceiver will switch from Standby to Normal mode if the
microcontroller holds SLPx_N HIGH for t
When the TJA1022 is in Reset mode, all input signals are ignored and all output drivers
are off. The TJA1022 switches to Reset mode when the voltage on V

Both transceivers enter Sleep mode after a power-on reset (e.g. after switching on V
The appropriate transceiver will switch automatically to Standby x mode if a remote LINx wake-up event is
detected in Sleep x mode.
RXDx will be LOW to indicate the source of the remote wake-up request; RXDx will go HIGH in response to
a positive edge on pin SLPx_N.
A positive edge on SLPx_N will trigger a transition to Normal mode; the transmitter will be off if TXDx is
LOW and will be enabled as soon as TXDx goes HIGH.
