Modes of Operation

The WUP bit in the register WAKE_STAT indicates detection of a wake-up pattern on the HS CAN bus. If the

transceiver is not in the Selective Sleep Sub-Mode AND if the transceiver detects a valid wake-up pattern, then

the WUP bit is set. An SPI clear command resets the bit. A wake-up is not executed under the following

conditions:

• A mode change to Normal-operating Mode is performed during the wake-up pattern.

• The maximum wake-up time tWAKE expires before a valid WUP is detected.

• The transceiver is powered down (VCC < VCC_POD AND VBAT < VBAT_POD).

5.7.2

Wake-up frame (WUF)

If the selective wake unit is enabled (SWK_EN =1), then the selective wake unit continuously monitors the

HS CAN Bus for a valid wake-up frame. If a valid WUF is detected, then the WUF bit in the register WAKE_STAT

is set to “1”. An SPI clear command resets the WUF bit. Chapter 7 describes the selective wake feature.
