Card Status Change
register’s
Battery Warning Change bit (see page
44
) is ‘1’. This bit is ignored when the card socket is in I/O
mode.
Bit 2 — Ready Enable
When this bit is ‘1’, a management interrupt will occur when the
Card Status Change
register’s
Ready Change bit (see page
44
) is ‘1’.
Bit 3 — Card Detect Enable
When this bit is ‘1’, a management interrupt will occur when the
Card Status Change
