Question

LXI H,2034H
MOV A,M
If accumulator can store 16 bit data??

Answer 1

Yes it can..

Answer 2

if anyone could help me

Answer 3

By operating 8 bits at a time..

Answer 4

how it can store 16 bit data as accumulator is 8 bit only

Answer 5

if we want to check the status of accumulator, then it will show which data,higher bit or lower bit data??

Answer 6

It can store 8 bit data first and then operate it..
Move this 8 bit data to other location after processing it..

Now, take the other 8 bit data and then again operate on it..
And move this data to other location...

Answer 7

@ganeshie8 do you have knowledge of Microprocessors Assembly language programming..

Can you help here ??

Answer 8

iam not satisfied with ur answer gopi

Answer 9

yes i can help u

Answer 10

accmulater have always memory of 16 bit data storage. double than a register.

Answer 11

u r totally wrong gini

Answer 12

@gsRttN , You are WRONG.. I am writing it in capital letters too..

Ha ha ha...

Answer 13

why? @waterineyes @dirtymind

Answer 14

In 8085 Microprocessor, Accumulator A is of 8 bits and not 16 bits, that is why...

Answer 15

ok ok sorry i was talking about microcontroller sorry its my mistake

Answer 16

It is okay..

Answer 17

here M stands for the memory , which by default has address which is the content located in the HL pair so when the command MOV A , M is fetched the control sees for the address which is the content of the HL pair which is a 4 digit data in hexadecimal and the content stored at this address is a 8 bit data which is being transferred to the accumulator. In 8085 processor the accumulator can never store the 16 bit data.

Answer 18

MOV A,M

fetches the 8bit data stored at M location in memory and places it in Accumulator
