2.4.3 Instruction Set

The instruction set has a simple organization, and features the generation of compact and optimized code through a

C compiler.

The instruction code size is reduced by making the basic instruction word length one byte. As a result, increases in

the code size of the assembler program can be kept to a minimum even though the instruction set is simple, with

data transfers to and from memory limited to load and store operations.
