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 transmitted nibbles
relative to (but not including) the transmit match location nibble will be compared.
Valid range is from 0x00
to 0x3D
Note: Triggering of transmit packets
matching at the Start-of-Frame Delimiter (SFD) requires that the Transmit Match
Location be configured to 0x00
. Additionally, all bits
within the Transmit Match Pattern field must be disabled from the compare by writing
the Transmit Match Mask registers to
0xFFFFFF
.
