Wake-Up in SBC Stop Mode
In SBC Stop Mode, if a wake-up is detected, it is signaled by the INT output and by the “WK CAN” SPI bit. It is
also signaled by RxDCAN put to low. The microcontroller should set the device to SBC Normal Mode, there is no
automatic transition to Normal Mode. In Normal Mode the transceiver can be enabled via SPI.
Wake-Up in SBC Restart or SBC Fail-Safe Mode
In SBC Restart or SBC Fail-Safe Mode, if a wake-up is detected, it is signaled by the “WK CAN” SPI bit.
Wake-Up in SBC Normal Mode
In SBC Normal Mode, if a wake-up is detected, it is signaled by the “WK CAN” SPI bit and INT output, and RxD
remains LOW.
