Name and Function
Power supply: For connection to the power supply.
All VCC pins should be connected to the system power
supply.
Port power supply pin. Connect all pins to the same
power supply.
Ground: For connection to ground
(0 V). All VSS pins should be connected to the system
power supply (0 V).
PLL power supply: Power supply for on-chip PLL
oscillator.
PLL ground: Ground for on-chip PLL oscillator.
PLL capacitance: External capacitance pin for on-chip
PLL oscillator.
Connects to a crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for typical
connection diagrams for a crystal oscillator and
external clock input.
Connects to a crystal oscillator.
The EXTAL pin can also input an external clock.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for typical
connection diagrams for a crystal oscillator and
external clock input.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for examples of
connections to a crystal oscillator.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23A, Clock Pulse Generator (H8S/2633,
H8S/2632, H8S/2631, H8S/2633F), for examples of
connections to a crystal oscillator.
System clock: Supplies the system clock to an external
device.
