7470/7471 Group
SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The 7470/7471 group uses the standard 740 family instruction set.
Refer to the table of 740 family addressing modes and machine in-
structions or the SERIES 740 <Software> User’s Manual for
details on the instruction set.
Machine-resident 740 family instructions are as follows:
The FST and SLW instruction cannot be used.
The MUL, DIV, WIT, and STP instruction can be used.
CPU Mode Register
The CPU mode register is allocated at address 00FB16.
This register contains the stack page selection bit.
