Select P18452 for the Device name and set the device clock to 8 MHz.Type the following delay program inside the C Code Editor

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 } }

Calculate manually the execution time of the delay program when R1= R2= 0 and compare it with that shown in the last figure
