CPU Mode Register
The CPU mode register is allocated at address 00FB16.
This register contains the stack page selection bit.
FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The 7477/7478 group 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 and SLW instruction cannot be used.
The MUL, DIV, WIT, and STP instruction can be used.
