OD = Open Drain
PD = Internal pulldown
PU = Internal pullup
Hi-Z = High Impedence
Float = IO is not powered and hence pin is not biased by the PHY
(2) PD only for Rgmii's isolate mode.

Note: For sleep mode entry vdda, vddio and vdd1p0 are supposed to be powered-down. See figure Required Implementation of Sleep Mode for further details.
