RST
RST - Input. The RST input pin contains a Schmitt voltage
input to recognize external active high reset inputs. The pin
also employs an internal pulldown resistor to allow for a
combination of wired OR external Reset sources.

XTAL2
XTAL1
XTAL1, XTAL2 - The crystal oscillator pins XTAL1 and
XTAL2 provide support for parallel resonant, AT cut
crystals. XTAL1 acts also as an input in the eve nt that an
external clock source is used in place of a crystal. XTAL2
serves as the output of the crystal amplifier.

PSEN
PSEN - Output. The Program Store Enable output. This
signal is commonly connected to external ROM memory as a
chip enable.
PSEN is active low. PSEN is driven high
when data memory (RAM) is being accessed through the bus
and during a reset condition.

ALE
ALE - Output. The Address Latch Enable output functions
as clock to latch the external address LSB from the
multiplexed address/data bus on Port 0. This signal is
commonly connected to the latch enable of an external 373
family transparent latch.ALE is forced high when the
DS80C310 is in a Reset condition.

AD0-7 (Port 0) - I/O. Port 0 is the multiplexed address/data
bus. During the time when ALE is high, the LSB of a
memory address is presented. When ALE falls to a logic 0,
the port transitions to a bidirectional data bus. This bus is
used to read external ROM and read/write external RAM
memory or peripherals. Port 0 has no true port latch and can
not be written directly by software. The reset condition of
Port 0 is high.

P1.0-P1.7
Port 1 - I/O. Port 1 functions as both an 8-bit bidirectional
I/O port and an alternate functional interface for Timer 2 I/O
and new External Interrupts. The reset condition of Port 1 is
with all bits at a logic 1. In this state, a weak pullup holds the
port high. This condition also serves as an input mode, since
any external circuit that writes to the port will overcome the
weak pullup. When software writes a 0 to any port pin, the
DS80C310 will activate a strong pulldown that remains on
until either a 1 is written or a reset occurs. Writing a 1 after
the port has been at 0 will cause a strong transition driver to
turn on, followed by a weaker sustaining pullup. Once the
momentary strong driver turns off, the port once again
becomes the output high (and input) state. The alternate
modes of Port 1 are outlined as follows:
