Filter 3 Offset
The Filter i Byte Mask defines which incoming frame bytes Filter i will examine to determine whether
or not this is a wake-up frame.
The Filter i command register controls Filter i operation.
The Filter i Offset register defines the offset in the frame’s destination address field from which the
frames are examined by Filter i.
DESCRIPTION
Must be zero (0)
Byte Mask: If bit j of the byte mask is set, the CRC machine processes byte number pattern - (offset
+ j) of the incoming frame. Otherwise, byte pattern - (offset + j) is ignored.
DESCRIPTION
Address Type: Defines the destination address type of the pattern. When bit is set, the pattern
applies
only to multicast frames. When bit is cleared, the pattern applies only to unicast frames.
RESERVED
Enable Filter: When bit is set, Filter i is enabled, otherwise, Filter i is disabled.
