TTS S22G G~~1166G GC CFF330000 300X CompactFlash Card Set Features – EFh Feature Supported Features 01h and 81h are used to enable and clear 8 bit data transfer modes in True IDE Mode. If the 01h feature command is issued all data transfers shall occur on the low order D[7:0] data bus and the -IOIS16 signal shall not be asserted for data register accesses. The host shall not enable this feature for DMA transfers.
TTS S22G G~~1166G GC CFF330000 300X CompactFlash Card Feature 03h allows the host to select the PIO or Multiword DMA transfer mode by specifying a value in the Sector Count register. The upper 5 bits define the type of transfer and the low order 3 bits encode the mode value. One PIO mode shall be selected at all times. For Cards which support DMA, one Multiword DMA mode shall be selected at all times. The host may change the selected modes by the Set Features command.
