Product specification
8-bit microcontroller
P83C562; P80C562
18 INSTRUCTION SET
The P8xC562 uses the powerful instruction set of the 80C51. Additional Special Function Registers are incorporated to
control the on-chip peripherals. The instruction set consists of 49 single-byte, 45 two-byte and 17 three-byte instructions.
When using a 16 MHz oscillator, 64 instructions execute in 0.75
μ
s and 45 instructions execute in 1.5
μ
s. Multiply and
divide instructions execute in 3
μ
s.
Tables 37 to 41 describe the Instruction set; Table 42 explains the Data addressing modes and the Hexadecimal
opcodes.
