1. When the ADC is used, refer to Table 60: 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. VDDSD12 is the external power supply for the PB2, PB10, and PE7 to PE15 I/O pins (the I/O pin ground is
internally connected to VSS). VDDSD3 is the external power supply for PB14 to PB15 and PD8 to PD15
I/O pins (the I/O pin ground is internally connected to VSS).
4. If T
A
is lower, higher P
D
values are allowed as long as T
J
does not exceed T
Jmax
.
5. In low power dissipation state, T
A
can be extended to this range as long as T
J
does not exceed T
Jmax
.
