In the 8085 microprocessor, the Program Status Word (PSW) contains important flags that reflect the state of the processor. Different instructions can affect these flags, such as the Zero Flag, Sign Flag, Carry Flag, and Parity Flag. For example, arithmetic operations like addition or subtraction can set or reset these flags based on the result of the operation. Consequently, the PSW is essential for conditional branching and decision-making within programs, as it provides the necessary status information determined by the executed instructions.
What else can I help you with?
What is the instruction for exit in 8085 microprocessors?
There is no exit instruction in the 8085. Do you mean return, as in from a function or interrupt? If so, the instruction is RET.
Is there a multiply instruction?
Not in the 8085.
How many instruction are there in 8085 mp?
There are 74 instructions in the 8085 microprocessor.
What happens when MUL CH instruction is executed?
MUL is not an 8085 instruction.
Which is the longest instruction in 8085 instruction set?
CALL, requiring 18 clock cycles.
How many bytes are there for jump instruction in 8085?
There are 74 instructions in the 8085 microprocessor.
What is NOP Instruction stands in 8085 microprocessor?
The NOP instruction is a no-operation instruction. It does nothing to the state of the machine, except to use some time. In the case of the 8085, it uses four clock cycles plus however many wait states are need to access the NOP instruction from memory.
What no of instruction will be execute by using only one clock pulse in 8085 microprocessor?
There are no instructions in the 8085 that execute in only one clock pulse. The minimum number of clock cycles is four; three for instruction fetch and one for instruction decode/execute.
According to word size how many instruction in 8085?
The 8085 is an 8 bit processor, so its word length is 8 bits.
How does the 8085 microprocessor instruction register work?
stores next instructions
PUSH Instruction in 8085 Micro processor?
Push instruction pushes two byte of data on the top of the stack.
What is operating frequency of microprocessor?
The operating frequency of 8085 is 3 mhz to 5 mhz
