4.0 Host Access Specification
4.1
Please refer to the CF Card standards for complete details on:


4.2
The host can access the CF Card by using the following interface modes with the Task Registers:
1. PC Card Memory Mode, Attribute Memory
2. PC Card Memory Mode, Common Memory
3. PC Card I/O Mode
4. True-IDE mode
Task File Register mapping for the interface modes
Byte/Word/Odd-byte mode mapping within each of the interface modes
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 CF 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).
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 CF Card is
mapped to PC Card Memory Mode by the Index bits in the Configuration Option Register
The CF Card can be accessed by Byte/Word/Odd Byte modes in PC Card I/O Mode. The CF 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.
The CF 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 CF Card
permits 8-bit accesses if the host issues a Set Feature Command to put the CF Card in 8-bit mode.
Parameter information that the CF 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.
