Indicates that one or both of the Pin Replacement Register CRdy, or
CWProt bits are set to "1". When the Changed bit is set, -STSCHG Pin
46 is held low if the SigChg bit is a "1" and the card is configured for
the I/O interface.
The host sets and resets this bit to enable and disable a state-change
"signal" from the Status Register, the Changed bit control pin 46 the
Changed Status signal. If no state change signal is desired, this bit
should be set to zero "0" and pin 46 (-STSCHG) signal will be held high
while the card is configured for I/O
The host sets this bit to one "1" if the card is to be configured in an 8-bit
I/O mode. The card is always configured for both 8- and 16-bit I/O, so
this bit is ignored.
This bit indicates whether the host requests the card to be in the power
saving or active mode. When the bit is "1" the card enters a power
down mode. When "0", the host requests that the card enter the active
mode. The PCMCIA Rdy/-Bsy value becomes BUSY when this bit is
changed. Rdy/-Bsy will not become Ready until the power state
requested has been entered. The card automatically powers down
when it is idle and powers back up when it receives a command
This bit represents the internal state of the interrupt request. This value
is available whether or not 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 "0".
