Product specification
P80CL580; P83CL580
21 INSTRUCTION SET
The P8xCL580 uses a powerful instruction set which permits the expansion of on-chip CPU peripherals and optimizes
byte efficiency and execution speed. Assigned opcodes add new high-power operation and permit new addressing
modes. The instruction set consists of 49 single-byte, 46 two-byte and 16 three-byte instructions. When using a 12 MHz
oscillator, 64 instructions execute in 1 µs and 45 instructions execute in 2 µs. Multiply and divide instructions execute in
4 µs.
For the description of the Data Addressing modes and Hexadecimal opcode cross-reference see Table 55.
