Read & Write
bit7
: Ring Indicate Enable.
Setting this bit to “0” for I/O card, the STSCHG#/RI# signal from the I/O card is used as the status
change signal STSCHG#. The current status of the signal is then available to the read from the Interface
Status Register and this signal can be configured as a source for the card status change interrupt.
Setting this bit to “1”, STSCHG#/RI# signal from the I/O card is used as a ring indicator signal and is
passed through to the RI_OUT# pin. For memory PC Card, bit has no function.
: PC Card Reset#. Setting this bit to “0” activates the Reset signal to the PC Card. The Reset signal will be
active until this bit is set to “1”.
: PC Card type. Setting this bit to “1” selects an I/O card. Setting this bit to “0” selects a memory card.
: INTR# Enable. Setting bit to “1” enables the card status change interrupt on the INTR# signal. If this bit
is set to “0”, the card status change interrupt is steered to one of the IRQn lines according bits7 through
4 in the card status change interrupt configuration register.
bit3 to bit0 : IRQn level selection (I/O card only).
