For the 8051 family of microcontrollers: i) Draw a representative memory map and explain how part of the data memory is able to share the same address space as the Special Function Registers in the case of the 8052. ii) When an 8051 device is switched on, which memory bank is active? Explain how you can switch to memory bank 1? iii) Explain why you should be very careful if you use a memory bank other than memory bank 0 if also using push and pop instructions. How can this issue be avoided?

Explain a XYZ method of transferring data from the computer's RAM to anotherpart of the computer without processing it using the CPU. As a sound card may need to accessdata stored in the computer's RAM, but since it can process the data itself, XYZ is a means ofhaving a peripheral device control a processor's memory bus directly. It permits the peripheral,such as a UART, to transfer data directly to or from memory without having each byte (or word)handled by the processor. Draw a diagram of the unit used in XYZ and how data is transferredusing this method. please sir i need full answer with diagram which mentioned in the question
