Unimplemented: Read as ‘0’
MIISCAN: MII Scan Enable bit
1 = PHY register at MIREGADR is continuously read and the data is placed in MIRD
0 = No MII Management scan operation is in progress
MIIRD: MII Read Enable bit
1 = PHY register at MIREGADR is read once and the data is placed in MIRD
0 = No MII Management read operation is in progress
Unimplemented: Read as ‘0’
Reserved: Maintain as ‘0’
NVALID: MII Management Read Data Not Valid bit
1 = The contents of MIRD are not valid yet
