Page 3: Introduction
I. INTRODUCTION The MSI-P563, shown in Fig. 1, is a general purpose I/O card designed for use with all PC/104 embedded systems. The card provides a versatile mixture of I/O functions for the designer which includes 24 TTL I/O lines, an IBM PC compatible asynchronous serial port, and three 16-bit counter/timers, as shown in the block diagram of Fig. - Page 4 50-PIN 82C55A CONNECTOR 24 TTL I/O LINES RS-232C 10-PIN INTERFACE CONNECTOR PC/104 16550 SERIAL I/O INTERFACE CHANNEL RS-422/485 10-PIN INTERFACE CONNECTOR 82C54 CLOCK 10-PIN INTERVAL INPUT CONNECTOR TIMER BUFFERS Figure 2.
