Name and function
Power: Connected to the power supply (+5 V or +3 V). Connect
both V
Ground: Connected to ground (0 V). Connect both V
system power supply (0 V).
Crystal: Connected to a crystal oscillator. The crystal frequency
must 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 must be double the
desired system clock frequency. See section 14, Clock Pulse
Generator 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 peripheral devices.
Reset: A low input causes the 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.
Data bus: 8-Bit bidirectional data bus.
Wait: Requests the CPU to insert T
when an off-chip address is accessed.
Read: Goes low to indicate that the CPU is reading an external
address.
Write: Goes low to indicate that the CPU is writing to an external
address.
Address Strobe: Goes low to indicate that there is a valid address
on the address bus.
