SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 7510 group uses the standard 740 family instruction set. Re-
fer to the table of 740 family addressing modes and machine
instructions or the SERIES 740 <Software> User’s Manual for de-
tails on the instruction set.
Machine-resident 740 family instructions are as follows:
The FST and SLW instruction are not available for use.
The STP, WIT, MUL, and DIV instruction can be used.
