Preamble
Writing a 1 suppresses the generation of the 32-bit PHY station
management preamble before the PHY register transfer. The internal
PHY of the 8430 does not require the preamble.
11
RW
0
Busy
Writing a 1 initiates the PHY register transfer. The hardware will clear
the bit when the operation completes.
10
RW
0
RegWr
Writing a 1 indicated the MDDAR data is to be written to the PHY.
Writing a 0 causes the PHY register to be read and the data placed in
the MDDAR .
