PCMCIA ATA drive definition
This document describes how the MiniStor AZA Protocol mapy onto the
PCMCIA interface. It resolves and clarifies the enhancements and
restrictions which result from the use of the PCMCIA interface with
the ATA Protocol.

 Differences between the ATA Standard and PCMCIA ATA
 a) The PCMCIA ATA specification provides Ready/Busy signal which can
    be used to prevent the host from accessing the drive before the
    card before the card is available following a power-up, hardware
    reset or PCMCIA Soft Reset.
 b) The PCMCIA ATA specification provides a Soft Reset protocol.
 c) The PCMCIA interface permits systems to address peripherals in
    more general ways than the traditional ATA specification allows.
 d) "High Impedance" state of INTRQ is replaced by interrupts
    disabled state.
 e) DMA is not a supported function in PCMCIA interface.

 I/O accesses are constrained at the PCMCIA interface as follows:
 - The host shall perform all word (16-bit) I/O accesses with A0 = 0.
 - If a card return -IOIS16 as active in response to the address on
   the bus then the host system is permitted to transfer 16 bits of
   data to the card in a single cycle, otherwise, the host system
   shall perform two 8 bit cycles: even byte then odd byte.

Addressing Modes - ATA Drive register set definition and protocol
There are three basic addressing spaces in the PCMCIA ATA card,
Attribute Memory, Common Memory, and Common I/O.

 Attribute Memory
 Attribute Memory contains the Card Information Structure (CIS Area)
 and the Card Configuration Registers (CCR). The information in
 Attribute Memory is accessed using a memory operation that asserts
 -REG, -CE1 along with the OE or -WE signals. The CIS starts at
 address 0h and is 256 bytes long of Read Only Sequential Access
 Memory. To be compatible with 8-bit hosts, the CIS information is
 stored on even-byte boundaries (0,2,4,...). It contains configuration
 information in a Metaformat, called tuples. (Tuple definitions can
 be found in the PCMCIA specification.) The CCR are used by the Host
 to configure the PC Card.

Card Information Structure
The Card Information Structure (CIS) is the cornerstone to the PCMCIA
standard. It is a variable-length chain (or linked list) of data
block or tuples. Byte 0 of each tuple contains the tuple function
code. Byte 1 contains the offset to the next tuple in the list. The
general function of the CIS is to allow the host to interrogate the
card as to its function and features. The host can then determine how
to configure its memory to accommodate or reject the card.

Card Configuration Registers
The PCMCIA Card Configuration Registers allow the host to select how
the card is to be addressed. It also allows for other interface
functions, like soft reset.
