Input. On a non-multiplexed bus,
these signals are dirctly connectoed to
the low bits of the host address bus.
On a multiplexed address/data bus,
A0/MUX is tied low, A1 is left open,
and A2 is tied to the address latch
enable signal of the host. A1 is
connectoed to an internal pull-up
resistor.
Input/Output. On a non-multiplexed
bus, these signals are used as the
data lines for the device. On a
multiplexed address/data bus,
AD0~AD2 act as the address lines
(latched by ALE) and as the low data
lines for the device. D3~D7 are
always used for data only. These
signals are connected to internal pull-
up resistors.
Signal ground.
An external crystal shoul be connected
to these pins. If an external TTL clock
is used instead, it must be connected
to XTAL1 with a 390 ohms pull-up
resistor, and XTAL2 should be left
floating.
Output. In normal mode, these active
low signals carry the transmit data
information, encoded in pulse format,
from the COM20020 to the media
driver circuitry. When the device is in
backplane mode, the PULSE1 signal
driver is programmable (push/pull or
open-drain), while the PULSE2 signal
provides a clock with frequency of
crystal/4. PULSE1 is connected to a
week internal pull-up resistor in
backplane mode.
Receive input. This signal carries the
receive data information from the line
receiver circuitry to the COM20020.
Transmit Enable output. This signal
used in backplane mode to enable the
line drivers for transmission. The
polarity of the signal is programmable
by grounding the PULSE2 pin. This
option is valid only in backplane mode.
Input. This active low signal issued by
the microcontroller executes a
hardware reset. It is used to activate
the internal reset circuitry within the
COM20020.

Interrupt output. This active low signal
is generated by the COM20020 when
an enabled interrupt condition occurs.
INTR returns to its inactive state when
the interrupt status condition or the
corresponding interrupt mask bit is
reset.
Chip select input. This active low
signal issued by the microcontroller
selects the COM20020 for an access.
Input. On a 68XX-like bus, this signal
is issued by the microcontroller as the
Read/Write signal to determine the
direction of data transfer. In this case,
a logic "1" selects a read operation,
while a logic "0" selects a write
operation. In this case, data is
actually strobed by the DS signal. On
an 80XX-like bus, this active low
signal is isuued by the microcontroller
to indicate a write operation. in this
case, a logic "0" on this pin, when the
COM20020 is accessed, enables data
from the data bus to be written to the
device.
Read/ Data strobe signal input. On a
68XX-like bus, this active low signal is
issued by the microcontroller as the
data strobe signal to strobe the data
onto the bus. On a 80XX-like bus, this
active low signal is issued by the
microcontroller to indicate a read
operation. In this case, a logic "0" on
this pin, when the COM20020 is
accessed, enables data from the
device to the data bus to be read by
the microcontroller.
