Pin No. Name In/Out Status Status Status Description

of OFF of ON of ON

No Token Token
1 A0/MUX In L L Pulse
2 A1 In L L L
3 A2/ALE In L L L

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.
4 AD0 In/Out L Pulse Pulse
5 AD1 In/Out L Pulse Pulse
6 AD2 In/Out L Pulse Pulse
8 D3 In/Out L Pulse Pulse
9 D4 In/Out L Pulse Pulse
10 D5 In/Out L Pulse Pulse
11 D6 In/Out L Pulse Pulse
12 D7 In/Out L Pulse Pulse

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.
7,12,14 GND Power GND GND GND
16 XTAL1 In L Pulse Pulse
17 XTAL2 In L Pulse Pulse

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.
18 PULSE1 Out L H Pulse
19 PULSE2 Out L L L

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.
20 RXIN In L H Pulse

Receive input. This signal carries the

receive data information from the line

receiver circuitry to the COM20020.
21 TXEN Out L L Pulse

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.
23 RESET IN In L H H

Input. This active low signal issued by

the microcontroller executes a hard-

ware reset. It is used to activate the

internal reset circuitry within the

COM20020.

No token Token

24 INTR Out L H Pulse

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.

25 CS In L H Pulse

Chip select input. This active low
signal issued by the microcontroller
selects the COM20020 for an access.

26 WR/DIR In L Pulse Pulse

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.

27 RD/DS In L L Pulse

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.

5-5. Power down detection circuit

IC48 : Detection IC
The power is supplied at CN16 from switching power supply unit.

When the VP voltage become more than 22V, the voltage appears at pin No.2 of IC48 through
the zener diode ZD2.
The detection IC outputs "High" signal from pin No.6 and its signal going to IC45.
Then, the signal "INTPWD" becomes "High" and going to GA2.
The GA2 outputs "Reset" signal and reset the all GAs.
