FUNCTIONAL DESCRIPTION
CENTRAL PROCESSING UNIT (CPU)
The 7510 group uses the standard 740 family instruction set. Re-
fer to the table of 740 family addressing modes and machine
instructions or the SERIES 740 <Software> User’s Manual for de-
tails on the instruction set.
Machine-resident 740 family instructions are as follows:
The FST and SLW instruction are not available for use.
The STP, WIT, MUL, and DIV instruction can be used.

CPU MODE REGISTER
The CPU mode register is allocated at address 003B16.
The CPU mode register contains the stack page selection bit and
the internal system clock selection bit.
(CPUM : address 003B16)
