80X CompactFlash Card

Transcend Information Inc.

CompactFlash Storage Card is always configured for both 8 and 16 bit I/O, so this bit is ignored.

-XE: For CompactFlash cards that do not support Power Level 1, this bit has value 0 and is not writeable.

Audio:This bit should always be zero for CompactFlash Storage cards.

PwrDwn: this bit indicates whether the host requests the CompactFlash Storage Card to be in the power saving or active

mode. When the bit is one (1), the CompactFlash Storage Card enters a power down mode. When PwrDwn is

zero (0), the host is requesting the CompactFlash Storage Card enter the active mode. The PCMCIA READY

value becomes false (busy) when this bit is changed. READY shall not become true (ready) until the power state

requested has been entered. The CompactFlash Storage Card automatically powers down when it is idle and

powers back up when it receives a command.

Int: this bit represents the internal state of the interrupt request. This value is available whether or not the I/O interface has

been configured. This signal remains true until the condition that caused the interrupt request has been serviced. If

interrupts are disabled by the -IEN bit in the Device Control Register, this bit is a zero (0).

4.5 Pin Replacement Register (Base + 04h in Attribute Memory)

CReady: this bit is set to one (1) when the bit RReady changes state. This bit can also be writt en by the host.

CWProt: this bit is set to one (1) when the RWprot c hanges state. This bit may also be written by the host.

RReady: this bit is used to determine the internal state of the READY signal. This bit may be used to determine the state

of the READY signal as this pin has been reallocated for use as Interrupt Request on an I/O card. When written,

this bit acts as a mask (MReady) for writing the corresponding bit CReady.

WProt: this bit is always zero (0) since the CompactFlash Storage Card does not have a W rite Protect switch. When

written, this bit acts as a mask for writing the corresponding bit CW Prot.

MReady: this bit acts as a mask for writing the corresponding bit CReady.

MWProt: this bit when written acts as a mask for writing the corresponding bit CW Prot.
