Electrical description
The CompactFlash memory card operates in three basic modes:
●
PC card ATA using I/O mode,
●
PC card ATA using memory mode,
●
True IDE mode, which is compatible with most disk drives.
The signal/pin assignments are listed in Table 8 where Low active signals have a ‘–’ prefix.
Pin 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. For
True IDE mode, pin 9 is grounded.
Table 9 describes the I/O signals. Inputs are signals sourced from the host while outputs 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 Section 4.2: Electrical specification for definitions of Input and Output type.
Table 8.
