GENERAL DESCRIPTION\nThe 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–bit single chip microcomputers, 4–bit data can be expanded by dividing between four I/O lines by executing the MOVDA, Pp, A and ORLDPp, A instructions.FEATURES\n?
