8.2
This device should not be used in a half-duplex network application. The final link to the device should be as short
as possible, (for example from an Ethernet Switch), in order to minimise the probability of corrupted packets on the
link.

Absolute Maximum Ratings -
Note: Exceeding these figures may cause permanent damage. Functional operation under these conditions is not guaranteed.
The core and PLL supply voltages must never be allowed to exceed the I/O supply voltage by more than 0.5 V
during power-up. Failure to observe this rule could lead to a high-current latch-up state, possibly leading to chip
failure, if sufficient cross-supply current is available. To be safe ensure the I/O supply voltage supply always rises
earlier than the core and PLL supply voltages.
