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.
System clock: Supplies the system clock to an external
device.
Mode pins: These pins set the operating mode.
The relation between the settings of pins MD2 to MD0
and the operating mode is shown below. These pins
should not be changed while the H8S/2633 Series is
operating.
