SINGLE-CHIP 8-BIT CMOS MICROCOMPUTER
MITSUBISHI MICROCOMPUTERS
3822 Group
FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The 3822 group uses the standard 740 family instruction set. Refer
to the table of 740 family addressing modes and machine instruc-
tions 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 STP, WIT, MUL, and DIV instruction can be used.
CPU Mode Register
The CPU mode register is allocated at address 003B
16
.
The CPU mode register contains the stack page selection bit and
the internal system clock selection bit.
