High Speed CAN Transceiver

Timing during Transition from Sleep to Normal Mode

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.
