CBWP_C—Card B Write-Protect Change
0 = Signal is changed.
1 = Signal is unchanged.
CBCD2_C—Card B Card Detect 2 Change
0 = Signal is changed.
1 = Signal is unchanged.
CBCD1_C—Card B Card Detect 1 Change
0 = Signal is changed.
1 = Signal is unchanged.
CBBVD2_C—Card B Battery Voltage 2/SPKR
Change
0 = Signal is changed.
1 = Signal is unchanged.
CBBVD1_C—Card B Battery Voltage 1/STSCHG
Change
0 = Signal is changed.
1 = Signal is unchanged.
Bit 23—Reserved
This bit is reserved and must be set to 0.
CBRDY_L—Card B RDY/IRQ
Low
0 = Signal is changed.
1 = Signal is unchanged.
CBRDY_H—Card B RDY/IRQ
High
0 = Signal is changed.
1 = Signal is unchanged.
CBRDY_R—Card B RDY/IRQ
Rising Edge
0 = Signal is changed.
1 = Signal is unchanged.
CBRDY_F—Card B RDY/IRQ
Falling Edge
0 = Signal is changed.
1 = Signal is unchanged.
Bits 28–31—Reserved
These bits are reserved and must be set to 0
Note:
Writing logic one to each bit reset its value (zero), except for bit 9, which is always
set to one. To reset the value of bits 24 and 25, you must remove the external
source of the interrupt.
