Bits 5:0 – RXLOCATION[5:0] Receive Match Location

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.
