I/O Function
Power
supply
VCC 62 65 F9, G10 Input For connection to the power supply.
Connect all V
CC
pins to the system power
supply.
CVCC 12 15 E2, F3 Input With a 5-V external power supply
(H8S/2238B used), connect a 0.1-µF
stabilization capacitance between this pin
and ground. Permanent damage on the
chip may result if the absolute maximum
rating of CV
CC
4.3 V is exceeded. Must not
connect the 5 V external power supply to
this pin.
With a 3-V external power supply
(H8S/2239, H8S/2238R, and H8S/2236R
used), connect this pin to the system
power supply. See section 25, Power
Supply Circuit, for connection examples.

Input For connection to the power supply (0 V).
Connect all VSS pins to the system power
supply (0 V).
Clock XTAL 63 66 F11 Input For connection to a crystal resonator. For
examples of crystal resonator connection
and external clock input, see section 23,
Clock Pulse Generator.
EXTAL 65 68 E11 Input For connection to a crystal resonator. This
pin can be also used for external clock
input. For examples of crystal resonator
connection and external clock input, see
section 23, Clock Pulse Generator.
OSC1 58 61 H11 Input Connects to a 32.768 kHz crystal
resonator. See section 23, Clock Pulse
Generator, for typical connection diagrams
for a crystal resonator.
