These input signals are used both to
select the card and to indicate to the
card whether a byte or a word
operation is being performed.
• -CE2 always accesses the odd
byte of the word.
• -CE1 accesses the even byte or
the odd byte of the word depending
on A0 and -CE2.
A multiplexing scheme based on A0,
-CE1, and -CE2 allows 8-bit hosts to
access all data on D0-D7. See
