1. When the ADC is used, refer to Table 49: ADC characteristics.
2. To sustain a voltage higher than V
DD
+0.3 V, the internal pull-up/pull-down resistors must be disabled.
3. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
Jmax
(see Table 14: Thermal characteristics).
4. In low power dissipation state, T
A
can be extended to this range as long as T
J
does not exceed T
Jmax
(see Table 14:
Thermal characteristics).
