PCI-to-PC Card (PCMCIA) Controller — PD6729
Datasheet
55
In Memory Card Interface mode, this bit is set to a ‘1’ when the BVD1/-STSCHG/-RI pin (see
Table 2) changes from high to low, indicating a battery dead condition. In I/O Card Interface mode,
this bit is set to a ‘1’ when the BVD1/-STSCHG/-RI pin changes from either high to low or low to
high. In I/O Card Interface mode, the function of this bit is not affected by bit 7 of the Interrupt
and General Control register. This bit is reset to a ‘0’ whenever this register is read.
Bit 1: Battery Warning Change
In Memory Card Interface mode, this bit is set to a ‘1’ when the BVD2/-SPKR/-LED pin changes
from high to low, indicating a battery warning. This bit is not valid in I/O Card Interface mode.
This bit is reset to a ‘0’ whenever this register is read.
Bit 2: Ready Change
In Memory Card Interface mode, this bit is a ‘1’ when a change has occurred on the RDY/-IREQ
pin (see Table 2). In I/O Card Interface mode, this bit always reads a ‘0’. This bit is reset to a ‘0’
whenever this register is read.
Bit 3: Card Detect Change
This bit is set to a ‘1’ when a change has occurred on the -CD1 or -CD2 pin (see Table 2). This bit
is reset to a ‘0’ whenever this register is read.
7.6
Management Interrupt Configuration
0
A transition (from high to low) on the BVD2/-SPKR/-LED pin has not occurred since this register
was last read.
1
A transition on the BVD2/-SPKR/-LED pin has occurred.
0
A transition on the RDY/-IREQ pin has not occurred since this register was last read.
1
A transition on the RDY/-IREQ pin has occurred.
0
A transition on neither the -CD1 nor the -CD2 pin has occurred since this register was last read.
1
A transition on either the -CD1 or the -CD2 pin or both has occurred.
