Datasheet
This register controls which status changes cause management interrupts as well as at which pin the
management interrupts will appear.
Bit 0: Battery Dead Or Status Change Enable
When this bit is a ‘1’, a management interrupt will occur when the Card Status Change register’s
Battery Dead Or Status Change bit (see “Bit 0: Battery Dead Or Status Change” on page 54) is a
‘1’. This allows management interrupts to be generated on changes in level of the BVD1/
-STSCHG/-RI pin.
Bit 1: Battery Warning Enable
When this bit is a ‘1’, a management interrupt will occur when the Card Status Change register’s
Battery Warning Change bit (see “Bit 1: Battery Warning Change” on page 55) is a ‘1’. This allows
management interrupts to be generated on changes in level of the BVD2/-SPKR/-LED pin. This bit
is not valid in I/O Card Interface mode.
Bit 2: Ready Enable
When this bit is a ‘1’, a management interrupt will occur when the Card Status Change register’s
Ready Change bit (see “Bit 1: Battery Warning Change” on page 55) is a ‘1’. This allows
management interrupts to be generated on changes in level of the RDY/-IREQ pin.
Bit 3: Card Detect Enable
When this bit is a ‘1’, a management interrupt will occur when the Card Status Change register’s
Card Detect Change bit (see “Bit 3: Card Detect Change” on page 55) is a ‘1’. This allows
management interrupts to be generated on changes in level of the -CD1 and -CD2 pins.
0
Battery Dead Or Status Change management interrupt disabled.
1
If Battery Dead Or Status Change bit is a ‘1’, a management interrupt will occur.
0
Battery Warning Change management interrupt disabled.
1
If Battery Warning Change bit is a ‘1’, a management interrupt will occur.
0
Ready Change management interrupt disabled.
1
If Ready Change bit is a ‘1’, a management interrupt will occur.
0
Card Detect Change management interrupt disabled.
1
If Card Detect Change bit is a ‘1’, a management interrupt will occur.
