Notes:
1.
Maximum DC undershoot below GND must be limited to either 0.5V or 10 mA, whichever is easier to achieve. During transitions, the device
pins can undershoot to –2.0V or overshoot to +7.0V, provided this overshoot or undershoot lasts less then 10 ns and with the forcing current
being limited to 200 mA.
2.
Stresses beyond those listed under Absolute Maximum Ratings might cause permanent damage to the device. These are stress ratings
only, and functional operation of the device at these or any other conditions beyond those listed under Operating Conditions is not implied.
Exposure to Absolute Maximum Ratings conditions for extended periods of time adversely affects device reliability.

Notes:
1.
VCCINT, VCCO, and VCCJ supplies can be applied in any order.
2.
At power up, the device requires the VCCINT power supply to monotonically rise to the nominal operating voltage within the specified TVCC rise
time. If the power supply cannot meet this requirement, then the device might not perform power-on-reset properly. See
Figure 6, page 11.
3.
If the VCCINT and VCCO supplies do not reach their respective recommended operating conditions before the OE/RESET pin is released,
then the configuration data from the PROM is not available at the recommended threshold levels. The configuration sequence must be
delayed until both VCCINT and VCCO have reached their recommended operating conditions.
