Where is the buffer in micro?

Question

Electronics

Good afternoon, tell me where the buffer is located in the MK and what it consists of, what tasks does it perform?
I tried to find it on the Internet, but I could not find its appearance, device and principle of operation.

Answer 1

Out of context, the question is meaningless. The microcontroller has, for example, ALU, RAM, ROM, registers, ports. There is no specific element with the generally accepted name "buffer" in microcontrollers.
But most likely you mean an area of ​​RAM allocated for a specific purpose.
