6.2 Instruction Set
The instruction set consists of the original 51 instructions with three formats and seven address modes
and additional instructions for the expanded address range. Each instruction can operate on word and
byte data. Table 6-1 shows examples of the three types of instruction formats; the address modes are
listed in Table 6-2.
Table 6-1. Instruction Word Formats
FORMAT
Dual operands, source-destination
Single operands, destination only
Relative jump, un/conditional
EXAMPLE
ADD R4,R5
CALL R8
JNE
OPERATION
R4 + R5 → R5
PC→ (TOS), R8 → PC
Jump-on-equal bit = 0
