8.5 I/O Transfer Function
8.5.1 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 Compact-
Flash 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.
8.6 Common Memory Transfer Function
8.6.1 Common Memory Function
The Common Memory Transfer to or from the CompactFlash card can be either 8 or 16 bits.
The CompactFlash card permits both 8 and 16 bit accesses to all of its Common Memory addresses.
