4.3
In order to reduce the current consumption to a minimum, but still supply a wake-up
circuit periodically, the SBC offers a Sleep Mode with Cyclic Sense (see
mode is entered via SPI command, and turns-off the integrated bus transceivers and
respective termination, as well as the main voltage regulator. The High-Side switch is
turned-on according to the SPI timings setting for cyclic sense, as there is the cyclic
sense period and the on-time. Upon a voltage level change at the monitoring/wake-up
pins or by a CAN or LIN message the SBC Sleep Mode will be terminated and the SBC
Standby Mode will automatically be entered. The respective RxD pin of the transceiver
that generated the wake-up will be pulled low.
