bit 15-0 MWTD<15:0>: MII Management Write Data bits
When written, a MII Management write cycle is performed using the 16-bit data and the pre-configured PHY
and Register addresses from the EMAC1MADR register.
Note: Both 16-bit and 32-bit accesses are allowed to these registers (including the SET, CLR and INV registers).
8-bit accesses are not allowed and are ignored by the hardware.

bit 15-0 MRDD<15:0>: MII Management Read Data bits
Following a MII Management Read Cycle, the 16-bit data can be read from this location.
Note: Both 16-bit and 32-bit accesses are allowed to these registers (including the SET, CLR and INV registers).
8-bit accesses are not allowed and are ignored by the hardware.
