StationAddress is used to define the individual destination address that the ST201 will respond to when receiving frames. Network addresses are generally specified in the form of 01:23:45:67:89:ab, where the bytes are received left to right, and the bits within each byte are received right to left (Isb to msb). The actual transmitted and received bits are in the order of 10000000 11000100 10100010 11100110 10010001 11010101.

BIT NAME
StationAddress Word0
StationAddress Word1
StationAddress Word2
BIT DESCRIPTION
The least significant word of the station, corresponding to address 0x54.
The second least significant word of the station, corresponding to address 0x56.
The most significant word of the station, corresponding to address 0x58.
The address comparison logic will compare the first 16 received destination address bits against Station- Address(0), the second 16 received destination address bits against StationAddress(1), and the third 16 received destination address bits against StationAddress(2). The value set in the StationAddress register is not inserted into the source address field of frames transmitted by the ST201. The source address field for every frame must be specified by the host system as part of the frame data contents.
