FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 3886 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:
[CPU Mode Register (CPUM)] 003B
The CPU mode register contains the stack page selection bit, the
processor mode bits specifying the chip operation mode, etc.
The CPU mode register is allocated at address 003B
Fig. 7 Structure of CPU mode register
The FST and SLW instructions cannot be used.
The STP, WIT, MUL, and DIV instructions can be used.
