GENERAL DESCRIPTION
The MSM82C43 is an input/output port expander device based on CMOS technology and
designed to operate at low power consumption levels.
In systems employing the MSM80C48/49 8鈥揵it single chip microcomputers, 4鈥揵it data can be
expanded by dividing between four I/O lines by executing the MOVDA, P
p
, A and ORLDP
p
,
A instructions.
