Indirect addressing mode in assembly language is similar to pointers in C$.$ Answer the following questions:

a$)$ What are the names of the three special indirect addressing mode registers used to store the addresses of variables in RAM?

b$)$ What is the logical size in bits of each of the registers identified in part a$)$ above?

c$)$ Write the assembly language command to load the address of the variable with name: $P_{V}al$ into one of the registers identified in part a$)$ above?

d$)$ What is the meaning of: movff PREINC$1,$ PORTC?

e$)$ What is the meaning of: movwf POSTINC$2,$w$,$a$?$

f$)$ Write an assembly language program to copy the values stored sequentially at addresses $036$ to $03F$ to PORTC using indirect addressing mode. There should be a delay of $100ms$ between each copy action. Assume you have the LoopTime subroutine, which implements a delay of $10ms.$ Hint: write a subroutine called "delay $100ms"$ to implement your delay.
