The value of the CRC calculated is based on the IEEE 802.3 Ethernet standard, it is taken over the bytes specified in
the wake up byte mask registers.
Wakeup Frame 1 Byte Mask 0 Register (0x44 – 0x45): WF1BM0
This register contains the first 16 bytes mask values of the Wake up frame 1 pattern. Setting bit 0 selects the first byte
of the Wake up frame 1, setting bit 15 selects the 16th byte of the Wake up frame 1.
Wakeup Frame 1 Byte Mask 1 Register (0x46 – 0x47): WF1BM1
This register contains the next 16 bytes mask values of the Wake up frame 1 pattern. Setting bit 0 selects the 17th byte
of the Wake up frame 1. Setting bit 15 selects the 32nd byte of the Wake up frame 1.
Wakeup Frame 1 Byte Mask 2 Register (0x48 – 0x49): WF1BM2
This register contains the next 16 bytes mask values of the Wake up frame 1 pattern. Setting bit 0 selects the 33rd byte
of the Wake up frame 1. Setting bit 15 selects the 48th byte of the Wake up frame 1.
Wakeup Frame 1 Byte Mask 3 Register (0x4A – 0x4B): WF1BM3
This register contains the last 16 bytes mask values of the Wake up frame 1 pattern. Setting bit 0 selects the 49th byte
of the Wake up frame 1. Setting bit 15 selects the 64th byte of the Wake up frame 1.
0x4C – 0x4F: Reserved
Wakeup Frame 2 CRC0 Register (0x50 – 0x51): WF2CRC0
This register contains the expected CRC values of the Wake up frame 2 pattern.
The value of the CRC calculated is based on the IEEE 802.3 Ethernet standard, it is taken over the bytes specified in
the wake up byte mask registers.
