1 Introduction
This document describes the implementation of PCMCIA / Compact Flash interface on
MC9328MX1 Application Development System (ADS). PCMCIA / Compact Flash interface
is connected to Chip Select 5 of External Interface Module (EIM). The hardware connection
between PCMCIA / Compact Flash interface and the DragonBall MX Processor are
described. Programming example to access Compact Flash Memory Card are given.
1.1 PCMCIA Overview
The PCMCIA specification is developed by Personal Computer Memory Card International
Association. It defines a standard 68 pin hardware interface for small removable 16 bit PC
card. A wide variety of hardware applications can be implemented using PC Cards. Typical
application include memory device, modems, ethernet controller etc. PC Card can be
operated in two distinct modes:
1.1.1 Memory Mode
The memory only interface support memory cards, but does not include signals which
support I/O Cards. It is the default interface whenever a card is inserted into a socket, as well
as the default interface for host to access the PC Card‘s Card Information Structure.
1.1.2 I/O Mode
The IO interface permits operation of either memory cards, I/O cards or multifunction cards
containing combinations of both memory and I/O devices.
Besides, the 26 bit address space of PC Cards are divided into attribute memory space and
common memory space by the REG# signal. Common memory space is where the storage
memory of the memory card lies on. It is referred by logic high of the REG# signal. Attribute
memory is a separately access section of card memory, and generally is used to access the
Card Information Structure and Function Configuration Registers. Only even locations are
accessible within attribute memory space.
