INSTRUCTION SET
The instruction set of the SM85CPU has the
following characteristics :
The instruction set is the result of subtle
design and consists of 67 types of basic
instructions.
The powerful bit manipulation instructions
includes plural bits transfer, logical operation
between bits, and the bit test and jump
instructions that incorporates a test and
condition branch in the same instruction.
There are transfer, operation and conditional
branch instructions for 16-bit. The actions of
transfer, operation and long jump for word
data can be processed in High speed.
There are arithmetic instructions for multi-
plication and division.
Multiplication : 8-bit x 8-bit
→
16-bit
Division : 16-bit x 16-bit
→
16-bit remaining
8-bit
23 types of memory addressing mode
By variety of memory addressing modes, the
accessing to RAM, ROM, and register file
can be operated .
