Name and Function
Power supply: For connection to the power supply.
All VCC1 and VCC2 * pins should be connected to
the system power supply.
Internal step-down voltage pin: A power supply
pin for the product, applicable to product lines that
have an internal step-down voltage. In the 5-V and
4-V versions, connect external capacitors to
stabilize the internal step-down voltage between
this pin and the VSS pin. Do not connect it to Vcc.
In the 3-V version, connect this pin and the VCC1
pin to the power supply for the system. For details,
See section 26, Electrical Characteristics.
Input/output buffer power supply: Power supply
pin for the port A input/output buffer.
Ground: All VSS pins should be connected to the
system power supply (0 V).
Connected to a crystal oscillator. See section 24,
Clock Pulse Generator, for typical connection
diagrams for a crystal oscillator and external clock
input.
