Slim-Link® Server Pin Descriptions (continued)
Pin Signal Model Description
16
DIO6
All
This pin provides access to Programmable Input/Output 24 from the AMD186
controller.
17
DIO7
All
This pin provides access to Programmable Input/Output 25 from the AMD186
controller.
18 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.
19 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.
20
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
21
INT1
All
INT1 provides the input for Interrupt Request 1 to the to the microcontroller.
22
INT3
All
INT3 provides the input for Interrupt Request 3 to the to the microcontroller.
23 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
Register of the AMD186 controller CLKOUT can be at 40 MHz, at the Power-
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.
24 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.
25
/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.
26
DGND
ALL
DGND provides the reference ground for the Slim-Link® Server’s Digital I/O
signals.
27
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.
