Notes :
1. These signals are required only for 16 bit access and not required when installed in 8 bit systems. Devices should allow for 3-state signals not to consume current.
2. Should be grounded by the host.
3. Should be tied to V
CC
by the host.
4. Optional for CE + Cards, Required for CompactFlash Storage Cards.
