Wakeup Frame 1 CRC0 Register (0x40 – 0x41): WF1CRC0
This register contains the expected CRC values of the Wake up frame 1 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.
Bit
Default Value
R/W
Description
15-0
0x0000
RW
WF1CRC0
Wake-up frame 1 CRC (lower 16 bits).
The expected CRC value of a Wake-up frame 1 pattern.
Wakeup Frame 1 CRC1 Register (0x42 – 0x43): WF1CRC1
This register contains the expected CRC values of the Wake up frame 1 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.

0x0000
RW
WF1CRC1
Wake-up frame 1 CRC (upper 16 bits).
The expected CRC value of a Wake-up frame 1 pattern.
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.

WF1BM0
Wake-up frame 1 Byte Mask 0.
The first 16 bytes mask of a Wake-up frame 1 pattern.
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.
Bit
Default Value
R/W
Description
15-0
0x0000
RW
WF1BM1
Wake-up frame 1 Byte Mask 1.
The next 16 bytes mask covering bytes 17 to 32 of a Wake-up frame 1 pattern.
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.
Bit
Default Value
