Specifications

 

 

PCI ENHANCED

Dual high performance PCI Bus Master EIDE interfaces are capable of supporting two

IDE ULTRA

IDE Type 4 disk drives each in a master/slave configuration. The interface supports

DMA/33

Ultra DMA/33 with synchronous DMA mode transfers up to 33MB per second.

INTERFACE (DUAL)

 

 

FLOPPY DRIVE

The SBC supports two floppy disk drives. Drives can be 360K to 2.88MB, in any

INTERFACE

combination.

 

SERIAL INTERFACE

Two high-speed FIFO (16C550) serial ports with independently programmable baud

 

rates are supported. The IRQ for each serial port has BIOS selectable addressing.

ENHANCED

The SBC provides a PC/AT compatible bidirectional parallel port and supports enhanced

PARALLEL

parallel port (EPP) mode and extended capabilities port (ECP) mode. The ECP mode is

INTERFACE

IEEE 1284 compliant. The IRQ for the parallel port has BIOS selectable addressing.

PS/2 MOUSE

The SBC is compatible with a PS/2-type mouse. The mouse connection can be made by

INTERFACE

using either the PS/2 mouse header or the bracket mounted PS/2 mouse mini DIN

 

connector. Mouse voltage is protected by a self-resetting fuse.

 

KEYBOARD

The SBC is compatible with an AT-type keyboard. The keyboard connection can be

INTERFACE

made by using either the keyboard header or the bracket mounted keyboard mini DIN

 

connector. Keyboard voltage is protected by a self-resetting fuse.

 

WATCHDOG TIMER

The watchdog timer is a hardware timer which resets the SBC if the timer is not

 

refreshed by software periodically. The timer is typically used to restart a system in

 

which an application becomes hung on an external event. When the application is hung,

 

it no longer refreshes the timer. The watchdog timer then times out and resets the SBC.

 

The watchdog timer has two levels of enable. First, the watchdog timer jumper must be

 

moved to the "enabled" position, which puts the watchdog timer under software control.

 

The second level involves software control of the watchdog's timer retriggering. Bit 6 of

 

the 82371EB GPOREG register at I/O address 437H must be set to a zero (0), which

 

blocks the triggering clock to the watchdog timer circuit, thus scheduling a hardware

 

reset in about 1.5 seconds.

 

 

To refresh the watchdog timer, the software in the application toggles bit 6 of the

 

GPOREG register. First the bit must be set to a one (1) to clear the watchdog timer

 

delay; then it must be set to a zero (0), which schedules a system reset in 1.5 seconds.

 

Toggling bit 6 of the GPOREG must occur within a period of less than 1.5 seconds to

 

insure that a system reset is not issued.

 

 

A set of watchdog timer software code and sample programs are available from

 

Technical Support.

 

POWER FAIL

A hardware reset is issued when on-board +5V voltage drops below 4.75 volts. In

DETECTION

addition, if the 3.3V Monitor jumper (JU15) is enabled, a reset is issued if 3.3V is below

 

tolerance. (See the Configuration Jumpers section later in this chapter.)
