2.Configuration and Status register (Address 202H)
This register is used for observing the state of the card.

Function
CHGED
(CARD->)
When CHGED bit is set to
“
1
”
, -STSCHG pin is held
“
L
”
at the condition of
SIGCHG bit set to
“
1
”
and the card configured for the I/O interface.
SIGCHG
(HOST->)
signal (-STSCHG pin). When the card is configured I/O card interface and this bit
is set
“
1
”
, -STSCHG pin is controlled by CHGED bit. If this bit is set to
“
0
”
,
-STSCHG pin is kept
“

.
IOIS8
(HOST->)
data bus (D7 to D0).
PWD
(HOST->)
this bit is reset to
“
0
”
, the card transfers to idle state (active mode). RRDY/BSY
bit on Pin Replacement Register becomes BUSY when this bit is changed.
RRDY/BSY will not become Ready until the power state requested has been
entered. This card automatically powers down when it is idle and powers back up
when it receives a command.
INTR
(CARD->)
available whether I/O card interface has been configured or not. This signal
remains true until the condition, which caused the interrupt request, has been
serviced. If the
–
IEN bit in the Device Control Register disables interrupts, this bit
is a zero.
bit5

INTR
bit0

R
This bit indicates that CRDY/-BSY bit on Pin Replacement register is set to
“
1
”
.
R/W
This bit is set or reset by the host for enabling and disabling the status-change
R/W
The host sets this field to
“
1
”
when it can provide I/O cycles only with on 8 bit
R/W
When this bit is set to
“
1
”
, the card enters sleep state (Power Down mode). When
