INSTRUCTION SET OF 8085
Instruction Set of 8085 An instruction is a binary pattern designed Example: RET Page 63 Branching Instructions Opcode Operand Description Rx |
How many Opcodes are there in 8085?
Each microprocessor has a set of instructions, a list which is provided by the microprocessor manufacturer.
The instruction set of a microprocessor is provided in two forms: binary machine code and mnemonics.
Microprocessor communicates and operates in binary numbers 0 and 1.What is the opcode in instruction format?
The operation code of an instruction is a group of bits that define operations such as addition, subtraction, shift, complement, etc.
An instruction must also include one or more operands, which indicate the registers and/or memory addresses from which data is taken or to which data is deposited.What is the format of a microprocessor?
In 8085 Instruction set, logical type there is one complement instruction with the mnemonic CMA.
Mnemonic CMA stands for “CoMplement the Accumulator”.
It performs1's complement operation on the current contents of the Accumulator, and the result is stored back in the Accumulator replacing its previous contents.
