Bits 10-15: PHY Physical Layer Address (PPA[4:0]) - Contains the address of the PHY to be accessed.
Bits 6-9: PHY MDIO Register (GM[4:0]) - Contains the address of register within the PHY to be accessed.
Bits 2-3: Clock Range (CR[1:0]) - Selects MDC clock frequency.
00 = divide input clock by 42
01 = divide input clock by 62
10 = divide input clock by 16
11 = divide input clock by 26
Bit 1: PHY MDIO Write (GW) - When set to 1, a write operation will be performed. When equal to zero, a read
operation will be performed.
Bit 0: PHY GMII Busy (GB) - This bit should be set to 1 when writing to SU.GMIIA. The MAC will clear the bit
when it is no longer busy. Do not write to GMIIA or GMIID while this bit is still set to 1. During read operations,
the data in SU.GMIID is invalid until this bit is equal to 0.
