Name and function
Power: Connected to the power supply (+5V). Connect both V
pins to the system power supply (+5V).
Ground: Connected to ground (0V). Connect all V
system power supply (0V).
Crystal: Connected to a crystal oscillator. The crystal frequency
should be double the desired system clock frequency. If an
external clock is input at the EXTAL pin, a reverse-phase clock
should be input at the XTAL pin.
External crystal: Connected to a crystal oscillator or external
clock. The frequency of the external clock should be double the
desired system clock frequency. See Section 16.2, “Oscillator
Circuit” for examples of connections to a crystal and external
clock.
System clock: Supplies the system clock to peripheral devices.
Enable clock: Supplies an E clock to E clock based peripheral
devices.
Reset: A Low input causes the H8/330 chip to reset.
Standby: A transition to the hardware standby mode
(a power-down state) occurs when a Low input is received at the
STBY pin.
Address bus: Address output pins.
