PD6710/’22 — ISA-to-PC-Card (PCMCIA) Controllers
Bit 1 — Speaker Is LED Input
0
Normal operation.
1
The PC Card -SPKR pin will be used to drive IRQ12 if Drive LED Enable (see “Bit 4 — Drive
LED Enable” on page 73) is set.
This bit changes the function of the BVD2/-SPKR/-LED pin (see Table 2 on page 20) from digital
speaker input 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
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 PC Card Standard may 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 PC Card Standard may 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 PC Card Standard may 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 PC Card Standard may be
controlled through use of this bit. This bit has no hardware control function when not in ATA mode.
