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.
Features 02h and 82h allow the host to enable or disable write cache in CompactFlash Storage Cards that
implement write cache. When the subcommand disable write cache is issued, the CompactFlash Storage Card
shall initiate the sequence to flush cache to non-volatile memory before command completion.
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.
