In order to reduce the current consumption to a minimum, the SBC offers a Sleep Mode
without Cyclic Sense (see
off the integrated bus transceivers and respective termination, main voltage regulator as
well as the High-Side switch. 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.

Note: To switch into Low Power Mode from Standby Mode the device should be
Data Sheet
switched into Normal Mode first. This is required to reset the CAN and LIN
transceiver to ensure correct wakeup as well as to ensure the correct function of
the RO pin when going to Sleep Mode. The time the device is in Normal Mode
before going to Low Power Mode should be long enough that the Vcc2 is up. This
can be released by a wait time or by reading the status of Vcc2 via SPI (bit13).
