FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The 3827 group uses the standard 740 family instruction set. Re-
fer to the table of 740 family addressing modes and machine
instructions or the 740 Family Software 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 (CPUM)] 003B
