Bits
Description
Bit 7
Bit 6
Write Protect : When this bit is set to "1",
WP signal is made to "H" and write protect is enabled forcibly.
Reg Active : When this bit is set to "1", Attribute Memory Space Access is enabled by the active
REG
signal output.
Card Detect and General Control Register
The Card Detect and General Control Register is shown below.

Card Detect and General Control Register (Read/Write)
Card Detect and General Control Register Description
Bit
Description
Bit 5
Bit 4
Status Change Mask
When this bit is set to 1, all interrupts due to status transitions are disabled. This masking is done
regardless of the status of each Enable bit of the Card Status Change Interrupt Configuration registers
(+05h and +45h).
Software Card Detect Interrupt :
When this bit is set to 1 while the card detect change enable bit 4 of the card status change interrupt
configuration register (+05h) is set to 1, a card detect change interrupt is generated the same as a
hardware card detect interrupt.
Note : The software card detection interrupt bit is always reset to 0 when the card status change
register is read.
