Wakeup Frame 0 CRC1 Register (0x32 – 0x33): WF0CRC1
This register contains the expected CRC values of the Wake up frame 0 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
WF0CRC1
Wake up Frame 0 CRC (upper 16 bits).
The expected CRC value of a Wake up frame 0 pattern.
Wakeup Frame 0 Byte Mask 0 Register (0x34 – 0x35): WF0BM0
This register contains the first 16 bytes mask values of the Wake up frame 0 pattern. Setting bit 0 selects the first byte
of the Wake up frame 0, setting bit 15 selects the 16th byte of the Wake up frame 0.
Bit
Default Value
R/W

WF0BM0
Wake up Frame 0 Byte Mask 0
The first 16 bytes mask of a Wake up frame 0 pattern.
Wakeup Frame 0 Byte Mask 1 Register (0x36 – 0x37): WF0BM1
This register contains the next 16 bytes mask values of the Wake up frame 0 pattern. Setting bit 0 selects the 17th byte
of the Wake up frame 0. Setting bit 15 selects the 32nd byte of the Wake up frame 0.
Bit
Default Value
R/W

WF0BM1
Wake up Frame 0 Byte Mask 1.
The next 16 bytes mask covering bytes 17 to 32 of a Wake up frame 0 pattern.
Wakeup Frame 0 Byte Mask 2 Register (0x38 – 0x39): WF0BM2
This register contains the next 16 bytes mask values of the Wake up frame 0 pattern. Setting bit 0 selects the 33rd byte
of the Wake up frame 0. Setting bit 15 selects the 48th byte of the Wake up frame 0.
Bit
Default Value
R/W

WF0BM2
Wake-up Frame 0 Byte Mask 2.
The next 16 bytes mask covering bytes 33 to 48 of a Wake-up frame 0 pattern.
Wakeup Frame 0 Byte Mask 3 Register (0x3A – 0x3B): WF0BM3
This register contains the last 16 bytes mask values of the Wake up frame 0 pattern. Setting bit 0 selects the 49th byte
of the Wake up frame 0. Setting bit 15 selects the 64th byte of the Wake up frame 0.
Bit
Default Value
R/W
Description
15-0
0x0000
