LDA is a read, while STA is a write.

    A T-state equals one clock cycle on the 8085 as far as I know. An M-cycle is made up of several (3 to 6) T-states. Examples of M-cycles are "Opcode Fetch" (which always is the first M-cycle of every instruction); "Memory Read" and "Memory Write". You can read more about the 8085's states and cycles in … The JZ instruction transfers control to the specified address if the value in the accumulator is 0. Otherwise, the next instruction is executed. Neither the accumulator nor any flags are modified by this instruction.

    Jun 04, 2013 · Instruction set-of-8085 1. Instruction Set of 8085 An instruction is a binary pattern designed inside amicroprocessor to perform a specific function. The entire group of instructions that a microprocessorsupports is called Instruction Set. 8085 has 246 instructions. Each instruction is represented by an 8-bit binary value. These 8-bits of binary value is called Op-Code orInstruction Byte. Jan 07, 2009 · The 8085 Instruction Set Instructions can be categorized according to their method of addressing the hardware registers and/or memory. Implied Addressing: The addressing mode of certain instructions is implied by the instruction’s function.

Assume the sum to be 8 bit number so you can ignore carries and store the sum at memory location 2210H.

    like JNZ These instructions transfer control from one part of a program to another The destination address must be within -128 and +127 bytes from the current instruction address because an 8-bit offset is used (28 = 256) Example: GoBack: DEC A ;Decrement A JNZ GoBack;If A is not zero, loop back Instruction Set CJNE , < src-byte >, rel Function: Compare and jump if not equal Description: CJNE compares the magnitudes of the tirst two operands, and branches if their values are not equal. The branch destination is computed by adding the signed relative displacement in the last instruction byte to the PC, after incrementing the
