Electrical description
The CompactFlash Memory Card operates in three basic modes:
The signal/pin assignments are listed in
types are Input, Output or Input/Output.
The configuration of the Card is controlled using the standard PCMCIA configuration
registers starting at address 200h in the Attribute Memory space of the memory card.
Table 9
are signals sourced from the Card. The signals are described for each of the three operating
modes.
All outputs from the Card are totem pole except the data bus signals that are bi-directional
tri-state. Refer to the section titled “Electrical Specifications” for definitions of Input and
Output type.
