igen jol remlett....van 8 bit memory mapped mod 1K cimablak kell neki

KJ

---------------------------

CF combines features from ISA bus, 16-bit PCMCIA, and ATA/IDE buses. It can
appear as I/O mapped, memory mapped, or as an IDE device. The IDE mode is
always 16-bit, but I/O and memory modes can present data as 8 or 16-bits.
These features make it the most flexible choice, allowing it to be used by
devices other than the PC - such as 8-bit processors in consumer
electronics.

The memory-mapped mode occupies 1K of address space, the top half containing
the selected page of data.

  a.. You can access all data on the card, through 8 or 16 bit data bus.
  b.. L = Low logic
  c.. H = High logic
  d.. NC = No Connection
  e.. NU = Not Used
  f.. D08-D15 required only for 16 bit access and not required when
installed in 8-bit systems.
1. Devices should allow for 3-state signals not to consume current.
2. Should be grounded by the host.
3. Should be tied to VCC by the host.
4. Optional for CF+ Cards, required for CompactFlash Storage Cards.
