What is Sta microprocessor?

In 8085 Instruction set, STA is a mnemonic that stands for STore Accumulator contents in memory. This instruction uses absolute addressing for specifying the destination. This instruction occupies 3-Bytes of memory.

What STA 4000H will do?

STAX D : “Store the contents of A register into memory location 4000H.” HLT : “Terminate program execution.”

What is INX microprocessor?

In 8085 Instruction set, INX is a mnemonic that stands for “INcrementeXtended register” and rp stands for register pair. This instruction will be used to add 1 to the present content of the rp. And thus the result of the incremented content will remain stored in rp itself.

What is M microprocessor?

In 8085 Instruction set, MOV r, M is an instruction where the 8-bit data content of the memory location as pointed by HL register pair will be moved to the register r. It occupies only 1-Byte in memory.

What is CMP in microprocessor?

In 8085 Instruction set, CMP is a mnemonic that stands for “CoMPareAccumulator” and hereR stands for any of the following registers, or memory location M pointed by HL pair. R = A, B, C, D, E, H, L, or M. This instruction is used to compare contents of the Accumulator with given register R.

What is Jnz microprocessor?

Microprocessor8085. In 8085 Instruction set, we are having one mnemonic JNZ a16, which stands for “Jump if Not Zero” and “a16” stands for any 16-bit address. This instruction is used to jump to the address a16 as provided in the instruction.

What are the main features of 8085 microprocessor?

The features of 8085 include:

  • It is an 8-bit microprocessor i.e. it can accept, process or provide 8-bit data.
  • It operates on a single +5V power supply connected at Vcc.
  • It operates on clock cycle with 50% duly cycle.
  • It has on chip clock generator this internal clock generator requires tuned circuit like LC,

What does INX H do in 8085?

In 8085 Instruction set, INX is a mnemonic that stands for “INcrementeXtended register” and rp stands for register pair. And it can be any one of the following register pairs. A register pair is generally used to store 16-bit memory address.
