4.5
The SBC Stop Mode has the advantage of reducing the current consumption to a
minimum, while supplying the microcontroller with its quiescent current during its power
saving mode (“Stop”). This mode is entered via SPI command, and turns-off the
integrated bus transceivers and respective termination, but the main voltage regulator
remains active.
A voltage level change at the monitoring / wake-up pins will, in contrast to the behavior
in Sleep Mode, generate a pulse at the WKO pin that is monitored by the microcontroller,
e.g. at an external interrupt input. In case the wake-up event was a CAN or LIN message,
the respective RxD pin will be pulled low. (The microcontroller itself has to take care of
switching SBC modes after a wake-up event notification (see
