FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The M37271MF-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 and
internal system clock selection bit. The CPU mode register is allo-
cated at address 00FB16.

Fix these bits to “1.”
Note: Please beware of this bit when programming because it
is set to “1” after the reset release.
XCOUT drivability selection bit
0 : Low drive
1 : High drive
Main colock (XIN–XOUT) stop bit
0 : Oscillating
1 : Stopped
Internal system clock selection bit
0 : XIN–XOUT selected (high-speed mode)
1 : XCIN–XCOUT selected (low-speed mode)
