Datasheet
4.0 Host Access Specification
4.1
Please refer to the ATA PC Card standards for complete details on:


4.2
The host can access the ATA PC Card by using the following interface modes with the Task Registers:




Task File Register mapping for the interface modes
Byte/Word/Odd-byte mode mapping within each of the interface modes
PC Card Memory Mode, Attribute Memory
The Card Information Structure (CIS) in Attribute Memory can be accessed by Byte/Word/Odd-byte modes in
PC Card Memory Mode. The -REG signal must be asserted when accessing Attribute Memory. The ATA PC
Card is mapped to PC Card Memory Mode by the Index bits in the Configuration Option Register. An example of
a CIS is listed in 4.3, Card Information Structure (CIS).
PC Card Memory Mode, Common Memory
Common Memory can be accessed in the Byte/Word/Odd Byte modes in PC Card Memory Mode. The -REG
signal must be de-asserted when accessing the Common Memory. The ATA PC Card is mapped to PC Card
Memory Mode by the Index bits in the Configuration Option Register
PC Card I/O Mode
The ATA PC Card can be accessed by Byte/Word/Odd Byte modes in PC Card I/O Mode. The ATA PC Card is
mapped to PC Card I/O Mode by the Index bits in the Configuration Option Register. The Index bits also select
Contiguous I/O, Primary I/O, or Secondary I/O mapping when using the PC Card I/O Mode.
True-IDE mode
The ATA PC Card is configured in a True IDE Mode of operation when the -ATASEL input signal is asserted
GND by the host at power up. In the True IDE Mode, Attribute Registers are not accessible from the host. The
Data Register is accessed in word (16-bit) mode at power up. The ATA PC Card permits 8-bit accesses if the
host issues a Set Feature Command to put the ATA PC Card in 8-bit mode. Parameter information that the ATA
PC Card uses in True IDE mode is returned when the Identify Drive command (ECh) is invoked. Refer to 4.4
Identify Drive Parameter Information for an example.
