1 Introduction

The Quatech MPAP-100 is a PCMCIA Type II (5 mm) card and is PCMCIA PC Card Standard Specification 2.1 compliant. It provides a single-channel RS-232 synchronous communication port. The base address and IRQ are configured through the PCMCIA hardware and software using utility programs provided by Quatech. There are no switches or jumpers to set.

The MPAP-100 uses a Zilog 85230-compatible Serial Communications Controller (SCC). The SCC can support asynchronous formats, byte-oriented synchronous protocols such as IBM Bisync, and bit-oriented synchronous protocols such as HDLC and SDLC. The SCC also offers internal functions such as on-chip baud

rate generators, and digital phase-lock loop (DPLL) for recovering data clocking from received data streams.

Because the PCMCIA 2.1 standard does not include a direct memory access (DMA) interface, the MPAP-100 supports only interrupt-driven communications. To compensate for the lack of DMA, the MPAP-100 is equipped with 1024-byte FIFOs for transmit and receive data. The FIFOs provide for high data throughput with very low interrupt overhead.

1.1System Requirements

16 bytes of contiguous I/O address space

one hardware interrupt (IRQ)

One available PCMCIA Type II socket
