Explanation / Answer

Code:-

LDI R0,5110

BRZ R0,SKIP_THE_BLOCK

ADI R0,10

STI R0,5110

SKIP_THE_BLOCK:

Explanation:-

LDI R0,5115 :- will copy the data stored in memory address 5110 (as per question ) into register R0

BRZ R0,SKIP_THE_BLOCK :- will check if the R0 register have value 0 or not if 0 then it will jump to SKIP_THE_BLOCK label and x=x+10 won't be done

ADI R0,10 :- will add the 10 to the value stored in the register i.e x

STI R0,5110 :- will store the resultant value in the address which is mentioned for x i.e 5110

SKIP_THE_BLOCK :- it is label i.e denotes end of the if block
