in 8085 only one accumulator used where in 6800 used two accumulator.
What does A represent in 8085 A microprocessor?
'A' means ACCUMULATOR.
What is the function of processor status word in 8085?
Processor status word ( PSW ) in the case of 8085 refers to the collection of the values of the flag register and accumulator. It is used with the command push: PUSH PSW With this command, the proccessor saves the value of accumulator (A) and the values of the flag bits to the stack.
If the 8085 add 89h and 79h specify the contents of the accumulator?
In the 8085, if the accumulator starts as 00H, then adding 89H and 79H to it results in a value of 02H with CARRY set.

What is ax or accumulator register?
Accumulator is a general purpose register.it is a 8 bit register in 8085. it stores the temporary results of a current operation doing by 8085.it is also called 'A' register
What is RAL in a microprocessor 8085?
RAL rotates the content of accumulator Left from Carry
What is STA in 8085?
STA is used to store the content of the accumulator in to the specified memory address. for example STA 4200. it stores the content of accumulator at 4200.
What the Difference between accumulator and register?
The accumulator is a general register that holds a value. It is also a special register that can be used as the target for the result of various arithmetic or logical computations. For instance, if you wanted to add two numbers, you could load the first into the accumulator, add the second to the accumulator, and then store the accumulator where wanted. The instruction register is an internal register that holds the value of the instruction opcode in order for the 8085 to decode and process the instruction. While it is shown on the Intel block diagram for the 8085, it is not directly accessible by the running program - it is for internal use only by the 8085.
How many bits are contained in the A register of a 8085 CPU?
8085 is a 8 bit microprocessor and so A register which is also known as accumulator is also 8 bit.
What the Difference between accumulator and instruction register?
Examples: /360: no accumulator 8080: A 6800: A and B 8086: AX ...
Difference between LDA and STA instruction in 8085?
In the 8085, the LDA instruction loads the accumulator from memory, while the STA instruction stores the accumulator to memory. LDA is a read, while STA is a write. LDA is opcode 3AH, while STA is opcode 32H.
