15.2 Example for interface with a 68-family microcontroller
VDD
Note:
This example is applicable
to the SBN1661G_M02.
The CS selection for the
SBN0080G_S18 and the
SBN0080G_S02 can be
decoded from the address
lines in the same way. For
application with the
SBN1661G_M18, which
does not have a CS input,
the CS output from the
decoder must be ORed with
C/D, E, and R/W.
