FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The M37221M6-XXXSP 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, SLW instruction cannot be used.
The MUL, DIV, WIT and STP instruction can be used.
CPU Mode Register
The CPU mode register contains the stack page selection bit. The
CPU mode register is allocated at address 00FB
16
.

Fix these bits to “1.”
Note :
Please beware of this bit when programming because it
is set to “1” after the reset release.
