Rp = Register pair 1. LXI Rp, 16 Bit data Rp ⇒ BC ≡ B DE ≡ D HL ≡ H SP Instruction word size ⇒ 3 Byte Operation ⇒ When this instruction will execute the 16-bit data will store in register pair Rp. [Rp ] ← 16-bit data Addressing Mode ⇒ Immediate Addressing Mode For example: LXI D 2059 H [D] = 20 … Read more
1. ANA R R ⇒ A, B, C, D, E, H, L, and M Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of Register R will get AND operation with the accumulator (A) content bit by bit and the final result will store in the accumulator [A]. Addressing Mode ⇒ If R ≠ … Read more
1. ADD R R ⇒ A, B, C, D, E, H, L, and M Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of Register R will get added to the accumulator (A) and the final result will store in the accumulator [A]. [A] ← [A] + [R] Addressing Mode ⇒ If R ≠ M … Read more

Addressing Mode ⇒ Implicit Addressing Mode 2. HLT no operand Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute further increment of the program counter … Read more
Rd = Destination register Rs = Source register 1. MOV Rd , Rs Rd & Rs ⇒ A, B, C, D, E, H, L, and M Instruction word size ⇒ 1 Byte Operation ⇒ When this instruction will execute the content of source register (Rs) will pass in the destination register (Rd). [Rd ] ← [Rs ] Addressing Mode ⇒ Register Addressing Mode For … Read more
An interrupt is a signal to the processor, generated by hardware or software indicating an immediate attention needed by an event. In this article, we will learn about hardware interrupts. In 8085 microprocessor, there is 5 hardware interrupts. S.No. Name of Interrupt Priority Vector address Masking type Types of trigger 1 TRAP Highest (1) 0024 … Read more
An interrupt is a signal that alerts the processor to an urgent condition, either originating from hardware or triggered by software, necessitating immediate attention. This mechanism allows the processor to temporarily halt its current operations and address the event requiring attention. In this article, we will focus on software interrupts. The 8085 microprocessor has eight … Read more
Active Power The actual amount of power being used, or dissipated, in a circuit is called True power or Active Power or real power. It is measured in watt (W) or kilowatt (kW) or MW. It is symbolized by the capital letter P. It has been seen that the power is consumed only in resistance. Reactive … Read more
Pumped Storage Plant These are a special type of power plant which works as ordinary hydropower plants for part of the time and when such plants are not producing power, they can be used as pumping stations which pump water from tail race to the head race. During this time, these plants utilize power available … Read more
Band Gap Theory The Band Gap theory explains the mechanism of conductor, insulators and semiconductor regarding the movement of free electrons from valence band to the conduction band. An energy band which separates the conduction band and the valence band is called Band gap or Forbidden band or Forbidden gap. Based on energy gap, the material … Read more
