Name and Function
On-chip power supply stabilizer pin: The VCL pin need
not be connected to the power supply. Connect this pin
to VSS via a 0.1 µF capacitor (placed close to the
pins).
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 ground: Ground for on-chip PLL oscillator.
PLL capacitance: External capacitance pin for on-chip
PLL oscillator.
Connects to a crystal oscillator.
See section 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), 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 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), for typical connection diagrams for a
crystal oscillator and external clock input.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), for examples of connections to a crystal
oscillator.
Subclock: Connects to a 32.768 kHz crystal oscillator.
See section 23B, Clock Pulse Generator (H8S/2633R,
H8S/2695), for examples of connections to a crystal
oscillator.
System clock: Supplies the system clock to an external
device.
