Datasheet
Note: This bit should be set to a ‘0’ if in Memory Card Interface mode.
This bit reconfigures the particular socket as an ATA drive interface. Refer to
for PCMCIA socket pin definitions in ATA mode.
Bit 1: Speaker Is LED Input
This bit changes the function of the BVD2/-SPKR/-LED pin (
to disk status LED input. When in I/O Card Interface mode or ATA mode, setting this bit to a ‘1’
reconfigures the BVD2/-SPKR/-LED input pin to serve as a -LED input from the socket.
Bit 3: A21
In ATA mode, the value in this bit is applied to the ATA A21 pin and is vendor-specific. Certain
ATA drive vendor-specific performance enhancements beyond the PCMCIA 2.1 standard can be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.
Bit 4: A22
In ATA mode, the value in this bit is applied to the ATA A22 pin and is vendor-specific. Certain
ATA drive vendor-specific performance enhancements beyond the PCMCIA 2.1 standard can be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.
Bit 5: A23/VU
In ATA mode, the value in this bit is applied to the ATA A23 pin and is vendor-specific. Certain
ATA drive vendor-specific performance enhancements beyond the PCMCIA 2.1 standard can be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.
Bit 6: A24/M/S*
In ATA mode, the value in this bit is applied to the ATA A24 pin and is vendor-specific. Certain
ATA drive vendor-specific performance enhancements beyond the PCMCIA 2.1 standard can be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.
Bit 7: A25/CSEL
In ATA mode, the value in this bit is applied to the ATA A25 pin and is vendor-specific. Certain
ATA drive vendor-specific performance enhancements beyond the PCMCIA 2.1 standard can be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.

Normal operation.
The PCMCIA -SPKR pin will be used to drive LED_OUT* if Drive LED Activity Enable (see
“Extension Control 1” on page
77) is set.
