1. Applies to all pins except MF<4:0> pins. Refer to
Table 24
for MF pin I/O Characteristics.
2. Parameter is guaranteed by design and not subject to production testing.
3. Does not apply to XI or TX_CLK pins. Refer to
Table 25
for clock input levels.
4. Applies to default MII driver level (bit 17.3= 0).
