7.7 Flags
The local wake-up source flag can only be set in a low power mode. When a wake-up
event on pin WAKE is detected (see
The local wake-up source flag is reset by entering a low power mode.
The remote wake-up source flag can only be set in a low power mode. When a bus
wake-up event is detected on the bus lines (see
source flag. The remote wake-up source flag is reset by entering a low power mode.

and STBN. If the undervoltage recovers the wake flag will be set and the transceiver
will enter the mode determined by the voltages on pins EN and STBN.

set, mode switching via pins EN and STBN is possible.
Star configuration: If an undervoltage is present on pin V
reset) pins EN, STBN, TXD and BGE are set LOW (internally) and pin TXEN is set
HIGH (internally). If the V
