ATA Control
Bit 0 — ATA Mode
This bit reconfigures the particular socket as an ATA drive interface. Refer to
Table 11-1 on
page 75
for PC Card socket pin definitions in ATA mode.
Bit 1 — Speaker Is LED Input
This bit changes the function of the BVD2/-SPKR/-LED pin (see
page 18
) from digital speaker in-
put to disk status LED input. When in I/O Card Interface mode or ATA mode, setting this bit to ‘1’
reconfigures the BVD2/-SPKR/-LED input pin to serve as a -LED input from the socket.
NOTE:
This bit should be set to ‘0’ if in Memory Card Interface mode.
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 PC Card Standard may be con-
trolled 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 PC Card Standard may be con-
trolled 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 PC Card Standard may be con-
trolled 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 PC Card Standard may be con-
trolled 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 PC Card Standard may be con-
trolled through use of this bit. This bit has no hardware control function when not in ATA mode.
