Wakeup Frame 2 Byte Mask 1 Register (Offset 0x0246): WF2BM1

This register contains the next 16 bytes mask values of the Wake up frame 2 pattern. Setting bit 0 selects the 17th byte

of the Wake up frame 2; setting bit 15 selects the 32nd byte of the Wake up frame 2.

Bit

Default

R/W

Description

15 - 0

WF2BM1

Wake up Frame 2 Byte Mask 1

The next 16 bytes mask covering bytes 17 to 32 of a wake up frame 2

pattern.

Wakeup Frame 2 Byte Mask 2 Register (Offset 0x0248): WF2BM2

This register contains the next 16 bytes mask values of the Wake up frame 2 pattern. Setting bit 0 selects the 33rd byte

of the Wake up frame 2; setting bit 15 selects the 48th byte of the Wake up frame 2.

Bit

Default

R/W

Description

15 - 0

WF2BM2

Wake up Frame 2 Byte Mask 2

The next 16 bytes mask covering bytes 33 to 48 of a wake up frame 2

pattern.

Wakeup Frame 2 Byte Mask 3 Register (Offset 0x024A): WF2BM3

This register contains the last 16 bytes mask values of the Wake up frame 2 pattern. Setting bit 0 selects the 49th byte

of the Wake up frame 2; setting bit 15 selects the 64th byte of the Wake up frame 2.

Bit

Default

R/W

Description

15 - 0

WF2BM2

Wake up Frame 2 Byte Mask 3

The last 16 bytes mask covering bytes 49 to 64 of a wake up frame 2

pattern.

Wakeup Frame 3 CRC0 Register (Offset 0x0250): WF3CRC0

This register contains the expected CRC values of the Wake up frame 3 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

R/W

Description

15 - 0

WF3CRC0

Wake up Frame 3 CRC (lower 16 bits)

The expected CRC value of a wake up frame 3 pattern.

Wakeup Frame 3 CRC1 Register (Offset 0x0252): WF3CRC1

This register contains the expected CRC values of the Wake up frame 3 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

R/W

Description

15 - 0

WF3CRC1

Wake up Frame 3 CRC (upper 16 bits)

The expected CRC value of a wake up frame 3 pattern.
