FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 3850 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 instructions cannot be used.
The STP, WIT, MUL, and DIV instructions can be used.
[CPU Mode Register (CPUM)] 003B
16
The CPU mode register contains the stack page selection bit, etc.
The CPU mode register is allocated at address 003B
