Push down on the retaining clips, moving them outward. The DIMM module, once released, will be forced up to an appropriate removal position. 2.4 Interrupt Routing All in ter rupts on the EBC- BX are routed to their re spec tive PC/104 bus pins. On board non- PnP peripherals, are routed to their typical usage interrupts using the jumper block at J19.
WinSystems - "The Embedded Systems Authority" 2.5 Power/Reset Connections Power is applied to the EBC-BX via the connector at J3 (Molex part number 26-60-7091). The pin definitions for J3 are given below. An optional push-button-reset (Normally Open) may also be routed into J3 if desired. Momentary closure to ground forces a hardware reset.

WinSystems - "The Embedded Systems Authority" 2.7 Real Time Clock/Calendar The EBC-BX contains an onboard Clock/Calendar within the Victory-66 chip. This clock is fully compatible with the MC146818A used in the original PC-AT computers. This clock has a number of features including periodic and alarm interrupt capabilities. In addition to the time and date keeping func tions, the sys tem con figu ra tion is kept within the CMOS RAM con tained in the clock sec tion.

When J24 pins 1-2 are jumpered, COM3 is enabled.
WinSystems - "The Embedded Systems Authority" The two primary serial ports, COM1 and COM2 are configurable for RS-422, RS-485 or J1708, with the ad di tion of op tional driver ICs (Win Sys tems P/N CK-75176-2). The con figu ra tion op tions for each of the supported modes are shown on the following pages. Connection to COM1 and COM2 is made through the Multi-I/O connector at J2. An adapter cable (P/N CBL- 247-1) is avail able from WinSystems to adapt to standard DB9 connectors.
WinSystems - "The Embedded Systems Authority" COM3/COM4 - RS-232 COM3 and COM4 are RS-232 only and are terminated at J4. An adapter cable is available from WinSystems (P/N CBL-173-1), which adapts J4 to two stan dard DB9M con nec tors.

WinSystems - "The Embedded Systems Authority" Register Details Port 0-5 I/O - Each I/O bit in each of the 6 ports can be individually programmed for input or output. Writing a '0' to a bit position causes the corresponding output pin to go to a High-Impedance state (pulled high by ex ter nal 10K ohm re sis tors). This al lows it to be used as an in put. When used in the in put mode, a read reflects the inverted state of the I/O pin, such that a high on the pin will read as a '0' in the register.
WinSystems - "The Embedded Systems Authority" 2.21 VGA Configuration The EBC-BX uses a fourth generation CRT/Flat panel Super VGA controller. It supports standard VGA output as well as a variety of Flat Panel Displays using optional Flat Panel Adapter (FPA) kits. The video on the EBC- BX uses the Asil iant 69000 se ries VGA con trol lers. The Asili ant con trol ler supports stan dard and super- VGA as well as Color and Mono chrome pan els with 8, 9, 12, 15, 16, 18,24 and 36-bit interfaces.

5 WS16C48 Programming Reference 5.1 Introduction This section provides basic documentation for the included I/O routines. It is intended that the accompanying source code equip the programmer with a basic library of I/O functions for the WS16C48 or can serve as the basis from which application specific code can be derived. 5.2 Function Definitions This section briefly describes each of the functions contained in the driver. Where necessary, short ex am ples will be pro vided to il lus trate us age.
WinSystems - "The Embedded Systems Authority" READ_BIT - Reads an I/O port Bit Syntax int read_bit(int bit_number); Description This function takes a single argument: bit_number - This is a value from 1 to 48 that indicates the I/O pin to read from. This func tion re turns the state of the I/O pin. A '1' is re turned if the I/O pin is low and a '0' is returned if the pin is high.
WinSystems - "The Embedded Systems Authority" SET_BIT - Set the specified I/O Bit Syntax void set_bit(int bit_number); Description This function takes a single argument: bit_number - a value between 1 and 48 specifying the port bit to be set. This function sets the specified I/O port bit. Note that set ting a bit re sults in the I/O pin actually going low. There is no return value and other bits in the same I/O port are unaffected.
WinSystems - "The Embedded Systems Authority" ENAB_INT - Enable Edge Interrupt, Select Polarity Syntax void enab_int(int bit_number, int polarity); Description This function requires two arguments: bit_number - A value from 1 to 24 specifying the appropriate bit polarity - Specifies rising or falling edge polarity detect. The constants RISING and FALLING are defined in “uio48.h” This function enables the edge detection circuitry for the specified bit at the specified polarity.
WinSystems - "The Embedded Systems Authority" CLR_INT - Clear the specified pending interrupt Syntax void clr_int(int bit_number); Description This function requires a single argument: bit_number - The specified bit number from 1 to 24 to reset the interrupt. This func tion clears a pend ing in ter rupt on the speci fied bit. It does this by dis abling andreenabling the in ter rupt.
WinSystems - "The Embedded Systems Authority" 5.3 Sample Programs There are three sample programs in source code form included on the EBC-BX diskette in the UIO48 directory. These programs are not useful by themselves but are provided to illustrate the usage of the I/O functions provided in UIO48C. FLASH.C This program was compiled with Borland C/C++ version 3.1 on the command line with: bcc flash.c uio48.c This program illustrates the most basic usage of the WS16C48.
6 APPENDIX A - I/O Port Map The following is a list of PC I/O ports. Ad dresses marked with a '-' are not used on the EBC-BX but their use should be carefully qualified so as not to conflict with other I/O boards. I/O addresses marked with a '+' are used on the EBC-BX board and are unique to the WinSystems’ design. I/O Addresses marked with '**' are generally un used and should be the ba sis for the first choices in I/O address selection.
