4.5 — 5.5 V Operating
2.0 — 5.5 V Idle/not used

2.0 —— V
Notes: 1. Do not leave the AVCC, and AVSS pins open even if the A/D converter and D/A
converter are not used.
Even if the A/D converter and D/A converter are not used, apply a value in the range
2.0 V to 5.5 V to AVCC by connection to the power supply (V
CC
), or some other method.
2. P67 to P60 include supporting module inputs multiplexed on those pins.
3. IRQ2 includes the ADTRG signal multiplexed on that pin.
4. P52/SCK0/SCL0 and P97/SDA0 are NMOS push-pull outputs in H8S/2138.
An external pull-up resistor is necessary to provide high-level output from SCL0 and
SDA0 (ICE = 1).
P52/SCK0 and P97 (ICE = 0) high levels are driven by NMOS in H8S/2138.
5. When ICE = 0. Low-level output when the bus drive function is selected is determined
separately.
6. The upper limit of the port 6 applied voltage is V
CC
+0.3 V when CIN input is not
selected, and the lower of V
CC
+0.3 V and AV
CC
+0.3 V when CIN input is selected.
When a pin is in output mode, the output voltage is equivalent to the applied voltage.
7. Current dissipation 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.
