266X CompactFlash Card

I/O Transfer Function

The I/O transfer to or from the CompactFlash Storage or CF+ Card can be either 8 or 16 bits. When a 16 bit accessible port is addressed, the signal -IOIS16 is asserted by the CompactFlash Storage or CF+ Card. Otherwise, the -IOIS16 signal is de-asserted. When a 16 bit transfer is attempted, and the -IOIS16 signal is not asserted by the CompactFlash Storage or CF+ Card, the system shall generate a pair of 8 bit references to access the word‘s even byte and odd byte. The CompactFlash Storage Card permits both 8 and 16 bit accesses to all of its I/O addresses, so -IOIS16 is asserted for all addresses to which the CompactFlash Storage responds. CF+ cards may or may not allow 16 bit register accesses and thus shall assert -IOIS16 as required. The CompactFlash Storage and CF+ Card may request the host to extend the length of an input cycle until data is ready by asserting the -WAIT signal at the start of the cycle.
