Low voltage 8-bit microcontrollers with
UART
P80CL31; P80CL51
19 INSTRUCTION SET
The P80CLx1 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
μ
s and 45 instructions execute in 2
μ
s. Multiply and divide instructions execute in
4
μ
s.
