Notes: 1. Do not leave the AVCC, AVref, and AVSS pins open even if the A/D converter is not used.
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 connecting to the power supply (V
CC
). The relationship between these two pins
should be AVref ≤ AV
CC
.
2. Ports A, G, I, P97, P86, P52, P42, and peripheral module outputs multiplexed on the pin
are
NMOS push-pull outputs.
An external pull-up resistor is necessary to provide high-level output from SCL0, SCL1, SDA0,
SDA1, SDA2, SCL2, ExSCLA, ExSCLB, ExSDAA, and ExSDAB (ICE bit in ICCR is 1).
Ports A, G, I, P97, P86, P52, and P42 (ICE bit in ICCR 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.
3. Indicates values when ICCS = 0, ICE = 0, and KBIOE = 0. Low level output when the bus drive
function is selected is rated separately.
4. Current consumption values are for V
IH
min = V
CC
– 0.2 V and V
IL
max = 0.2 V with all output pins
unloaded and the on-chip pull-up MOSs in the off state.
