CHIP CONTROL REGISTERS
6.5
Card Status Change
This register indicates the source of a management interrupt generated by the CL-PD67XX.
NOTE:
The corresponding bit in the
Management Interrupt Configuration
register must be set to ‘1’ to enable
each specific status change detection.
Bit 0 — Battery Dead Or Status Change
When the socket is configured for memory card support, this bit is set to ‘1’ when a BVD1 battery
dead high-to-low transition has been detected. When the socket is configured for I/O card support,
this bit is set to ‘1’ when the BVD1/-STSCHG pin (see
page 19
) changes from either high to low
or low to high. This bit is reset to ‘0’ whenever this register is read. In I/O Card Interface mode,
function of this bit is not affected by bit 7 of the
Interrupt and General Control
register.
Bit 1 — Battery Warning Change
When a socket is configured for memory card support, this bit is set to ‘1’ when a high-to-low tran-
sition on BVD2 occurs indicating a battery warning was detected. This bit should be ignored when
the socket is configured for I/O card support. This bit is reset to ‘0’ whenever this register is read.
Bit 2 — Ready Change
When this bit is ‘1’, a change has occurred in the card RDY/-IREQ pin (see
page 17
). This bit will
always read 0 when the card is configured as an I/O card. This bit is reset to ‘0’ whenever this reg-
ister is read.
Bit 3 — Card Detect Change
When this bit is ‘1’, a change has occurred on the -CD1 or -CD2 pins (see
page 18
). This bit is
reset to ‘0’ whenever this register is read.
