ok I know but can you tell me another wayOne way would be reading the datasheet.
ok I am asking you simple question design 8 bit controller so what will you do i think you need specification how you will decide what specification need for your controller controller same work i am doing I am looking specification for controllerHi,
You mean like by counting the pins or something, or by examining the in-circuit electrical signals?
You can not tell by counting the pins.
Without examining the signals you'd have to look at the die and know something about die architecture.
Examining the signals you'd have to be able to decode the data buss.
By examining the circuit board (mother board) you might be able to tell from the other chip types but that's tricky.
I cannot see a single question mark, so that does not qualify as a question. After reading it four times I am starting to have some idea what you meant, but still it is a bit too mixed up together. Could you rephrase that so that we know what exactly you are asking?ok I am asking you simple question design 8 bit controller so what will you do i think you need specification how you will decide what specification need for your controller controller same work i am doing I am looking specification for controller
Many 8 bit CPUs have 16 bit address pointers and data pointers. These pointers can be incremented (a=a+1) with out going through the CPU. Example: get data at (pointer) and pointer=pointer+1. This is one instruction.I cannot see a single question mark, so that does not qualify as a question.

Basic thing is that 8 bit cpu can do operations on 8bit chunks of data. Like adding two 8bit numbers or doing an OR on two 8bit numbers.
On the other hand most 8bit micorocontrollers will have much more than just 256 bytes of memory (that 8 bits allow) so the address could be for example 16bit, but you would need two operations to say increment that adress, since the cpu can only process 8 bits at a time.

You have no need to apologize.... We are just trying to get the proper requirements so we can help you!!I am sorry for my bad English. can you tell me, what is difference between data bit and instruction bit?
what is data path and instruction path in micro controllerYou have no need to apologize.... We are just trying to get the proper requirements so we can help you!!
Instructions (bytes) are located in code memory (Flash nowadays) and data bytes are located in sram or EEprom
Instructions are used to tell the CPU what to do with the data...
