Description

This signal is used during Memory Cycles to distinguish

between Common Memory and Register (Attribute) Memory

accesses. High for Common Memory, Low for Attribute

Memory.

The signal must also be active (low) during I/O Cycles when

the I/O address is on the Bus.

This is a DMA Acknowledge signal that is asserted by the

host in response to DMAREQ to initiate DMA transfers.

While DMA operations are not active, the card shall ignore

the –DMACK signal, including a floating condition.

If DAM operation is not supported by a True-IDE Mode only

host, this signal should be driven high or connected to VCC

by the host.

A host that does not support DMA mode and implements

both PCMCIA and True-IDE modes of operation need not

alter the PCMCIA mode connections while in True-IDE

mode as long as this does not prevent proper operation all

modes.

When the pin is high, this signal resets the Compact Flash

Card. The card is Reset only at power up if this pin is left

high or open from power-up. The card is also reset when the

Soft Reset bit in the Card Configuration Option Register is

set.

This signal is the same as the PC Card Memory Mode signal.

In the True IDE Mode this input pin is the active low

hardware reset from the host.

Voltage Sense Signals. –VS1 is grounded so that the

Compact Flash Card CIS can be read at 3.3 volts and –VS2 is

open and reserved by PCMCIA for a secondary voltage.

This signal is the same for all modes.

This signal is the same for all modes.
