WAKE-UP FROM BSD INTERFACE
The MCU core can be woken up from power-down via the BSD
physical interface. Before entering power-down mode, user
code should enable the start condition interrupt (LHSCON0[3]).
When this interrupt is enabled, a high to low transition on the
LIN/BSD pin generates an interrupt event and wakes up the
MCU core.
