TS32M~1GCF80		80X CompactFlash Card

port is addressed, the signal -IOIS16 is asserted by the CompactFlash Storage. 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, 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. The CompactFlash Storage 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.
