* Exceeding these figures may cause permanent damage. Functional operation under these conditions is not guaranteed. Voltage measurements are with respect to ground (VSS) unless otherwise stated.
* 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  urrent is available. To be safe ensure the I/O supply voltage supply always rises earlier than the core and PLL supply voltages.
