Slim-Link® Server

DIO6

All

This pin provides access to Programmable Input/Output 24 from the AMD186

controller.

DIO7

All

This pin provides access to Programmable Input/Output 25 from the AMD186

controller.

DIO8(INT2)

All

This pin provides access to Programmable Input/Output 31 from the AMD186

controller. It also provides the input for Interrupt Request 2 to the Slim-Link®

Server.

DIO9(INT4)

All

This pin provides access to Programmable Input/Output 30 from the AMD186

controller. It also provides the input for Interrupt Request 4 to the Slim-Link®

Server.

NMI

All

This input provides access to the non-maskable interrupt to the microcontroller.

This is the highest priority interrupt available on the Slim-Link® Server

INT1

All

INT1 provides the input for Interrupt Request 1 to the to the microcontroller.

INT3

All

INT3 provides the input for Interrupt Request 3 to the to the microcontroller.

CLKOUT

AWC86

This output provides the clock signal for the rest of the embedded control system

in the AWC86. Depending upon the value set in the System Configuration

Save frequency, or may be tri-stated. The Power-Save frequency is programmable

from 1/2 (20 MHz) to 1/128 (312.5 KHz) of the system clock

VREF

AWC86A

This input provides the reference voltage for the Slim-Link® Server analog inputs.

VREF should not exceed VCC by more than 50 millivolts.

RESETOUT

AWC86

This output provides an active high reset pulse for the complete embedded

control system. The duration of the reset pulse is typically 13 milliseconds. The

reset pulse is sent each time power is applied to the AWC86 or the /RESET

signal is driven low.

V.BAT

AWC86A

This input the battery backup voltage for the AWC86A Real-Time Clock. A

minimum of two volts must be maintained on VCC1 to maintain the Real-Time

Clock.

/RESET

ALL

This input allows an the Slim-Link® Server to be reset from an external source.

Reset must be held low for a minimum of one millisecond to initiate a Slim-Link

Server reset.

DGND

ALL

DGND provides the reference ground for the Slim-Link® Server’s Digital I/O

signals.

GND

AWC86

This signal provides the reference ground for the AWC86 I/O signals.

AGND

AWC86A

This signal provides the reference ground for the AWC86A Analog I/O signals.
