INSTRUCTION SET
5-1
INSTRUCTION SET DESCRIPTION
Abbreviations and symbols table specifies internal architecture, instruction operand and operational symbols.
As mentioned before, JP and CALL instructions are executed normally only when SF is high. If SF is low, the
program executes NOP instruction instead of them and sets SF to high. And then, the program executes a next
instruction. In addition, JPL and CALL are long jump and long call instructions which consists of PAGE and
JP/CALL instructions.
