5.4.2.2 Wake-up Pattern (WUP)
A WUP is signaled on the bus by two consecutive dominant bus levels for at least t_Wake1, each separated by a
recessive bus level.

5.4.2.3 Wake-up Frame (WUF)
The wake-up frame is defined in ISO/WG11898-6 proposal chapter 5.2.5.2.
Only CAN frames according ISO11989-1 are considered as potential wake-up frames.
A bus wake-up shall be performed, if selective wake-up function is enabled and a "valid WUF" has been received.
The transceiver may ignore up to four consecutive CAN data frames that start after switching on the bias.
A received frame is a “valid WUF” in case all of the following conditions are met:
• The ID of the received frame is exactly matching a configured ID in the relevant bit positions. The relevant bit
positions are given by an ID mask. The ID and the ID mask might have either 11 bits or 29 bits.
• The DLC of the received frame is exactly matching the configured DLC.
