* Control for setup is the falling edge of
RD
or
WR
. Control for hold is the falling edge of
RD
or the rising edge
of
WR
.
NOTE: Asserting ALE,
CS
, and
RD
or
WR
concurrently can cause unintentional register accesses. When using
non-8031 compatible processors, care must be taken to prevent this from occurring when designing the
interface logic.
