1. Do not leave the AVCC, AVref, and AVSS pins open even if the A/D converter is not used.
2. P80/SCL0 to P83/SDA1 and PC0/SCL2 to PC3/SDA3 are NMOS push-pull outputs.
3. Current consumption values are for V

5. Except for flash memory programming/erasing.
2. When driving a Darlington transistor directly, always insert a current-limiting resistor in
unloaded and the on-chip pull-up MOSs in the off state.
the output line, as shown in figure 24.1.
Even if the A/D converter is not used, apply a value in the range from 3.0 V to 3.6 V to the AVCC
and AVref pins by connection to the power supply (VCC). The relationship between these two pins
should be AVref ≤ AVCC.
An external pull-up resistor is necessary to provide high-level output from SCL0 to SCL3 and
SDA0 to SDA3 (ICE bit in ICCRA is 1).
P80 to P83 and PC0 to PC3 (ICE bit in ICCRA is 0) high levels are driven by NMOS. An external
pull-up resistor is necessary to provide high-level output from these pins when they are used as an
output.
