FUNCTIONAL DESCRIPTION
Central Processing Unit (CPU)
The 7534 Group uses the standard 740 family instruction set. Refer
to the table of 740 family addressing modes and machine-language
instructions or the 740 Family Software Manual for details on each
instruction set.
Machine-resident 740 family instructions are as follows:
1. The FST and SLW instructions cannot be used.
2. The MUL and DIV instructions cannot be used.
3. The WIT instruction can be used.
4. The STP instruction can be used.
[CPU Mode Register] CPUM
The CPU mode register contains the stack page selection bit.
This register is allocated at address 003B
16
.
Note on stack page
When 1 page is used as stack area by the stack page selection bit,
the area which can be used as stack depends on RAM size. Espe-
cially, be careful that the RAM area varies in Mask ROM version,
One Time PROM version and Emulator MCU.

Switching method of CPU mode register
Switch the CPU mode register (CPUM) at the head of program after
releasing Reset in the following method.

Switch the clock division ratio
selection bits (bits 6 and 7 of CPUM)
After releasing reset
Main routine
Start with an on-chip oscillator (
Note
)
Switch to other mode except an on-chip oscillator
(Select one of 1/1, 1/2, and 1/8)
Note
. After releasing reset the operation starts by starting an on-chip oscillator automatically.
Do not use an on-chip oscillator at ordinary operation.
Wait until establish ceramic oscillator
clock.
