Location in nibbles
within the Ethernet packet relative to, but not including, the Start-of-Frame Delimiter
(SFD) at which the pattern matcher will activate. The six previous received nibbles
relative to (but not including) the receive match location nibble will be compared.
Valid range is from 0x00
to 0x3D
.Note: Triggering of receive packets matching
at the Start-of-Frame Delimiter (SFD) requires that the Receive Match Location be
configured to 0x00
. Additionally, all bits within the
Receive Match Pattern field must be disabled from the compare by writing the Receive
Match Mask registers to
0xFFFFFF
.
