8. FUNCTION BLOCK DESCRIPTION
8.1 CENTRAL PROCESSING UNIT (CPU)
This microcomputer uses the standard 740 Family instruction set.
Refer 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.
Availability of 740 Family instructions are as follows:
The FST, SLW instruction cannot be used.
The MUL, DIV, WIT and STP instructions can be used.
8.1.1 CPU Mode Register
The CPU mode register includes a stack page selection bit and inter-
nal system clock selection bit. The CPU mode register is allocated at
address 00FB16.
