5.2
The host can access the CF Card by using the following interface modes with the Task Registers:
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 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 5.3, 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 CF Card is mapped to PC
Card Memory Mode by the Index bits in the Configuration Option Register
PC Card I/O Mode
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.
True-IDE mode
The CF Card is configured in a TrueIDE Mode of operation when the -ATASEL input signal is asserted
GND by the host at power up. In the TrueIDE 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 TrueIDE mode is returned when the Identify Drive command (ECh) is invoked. Refer to
5.4 Identify Drive Parameter for an example.
