Card Status Change Register
PCMCIA Interface
Bit Description
7
Software Card Detect Change
6
Card Detect Change
5
Interrupt request from PCMCIA card
0: No interrupt request (for pulse mode interrupts)
1: pulse mode interrupt requested (IREQ pin from card)
4
If Ring Indicate enable bit is 0 and nSTSCHG/nRI is 0, then this bit is 1.
Otherwise this bit is 0.
3
Ring Indicate Change
2
Ready Change
1
Battery Warning Condition. No meaning in I/O Card
0
Battery Warning Condition. No meaning in I/O Card
Table 10-6: Card Status Change Register Bits
The Card Status Change Register contains the status for the sources of the card status change
interrupt. These sources can be enabled to generate a card status change interrupt by setting the
corresponding bit in the Card Status Change Interrupt Configuration Register. There are two
ways to reset this register:
• Read the Card Status Change Register
• Write back in the Card Status Change Register after setting Explicit Write Back Card
Status Change Acknowledge bit to 1 in the Global Control Register
Power and RESETDRV Control Register
This register controls the power.
Bit Description
7
Host Bus Adapter SoftReset
Setting this bit resets the HBA
6
Output Enable.
If this bit is set to 0, the output signals nCE2, nCE1, nCIORD, nCIOWR,
nOE, nREG, RESET, and nWE are tristated.
5
Auto Power Switch Enable.
1: Automatic socket power switching based on card detect is enabled.
4
Socket Power Control bit
0: Vcc5EN = 1, Vcc3EN = 1
1: Bit 1 and Bit 0 determine Vcc5EN, Vcc3EN Values
