For the following assembly code give an explanation as well.

Device is P18452 and deviceclock is 8 MHZ, it is done is mikroC.

void main() { asm { MOVLW 4 MOVWF R1 MOVLW 3 N1: MOVWF R2 N2: DECF R2 BNZ N2 DECF R1 BNZ N1 NOP HERE: BRA HERE } }

1a. Modify the program such that R1= R2= 0.

1b. How many files are generated in your experiment 1 project? List them all. 1c. How many bytes of RAM and ROM are used? Justify. 1d. Calculate manually the execution time of the delay program when R1= R2= 0 and compare it with that shown in the last figure.
