2.5 I/O Transfer Function
2.5.1 I/O Function
The I/O transfer to or from the CompactFlash card can be either 8 or 16 bits. When a 16-bit accessible port is
addressed, the signal -IOIS16 is asserted by the CompactFlash 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 card, the system
must generate a pair of 8-bit references to access the word’s Even Byte and Odd Byte. The CompactFlash 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 card responds.
