Assuming 8 bits twos complement binary representation what is the result of converting the decimal value -12 into hexadecimal? Yantnz: Ox10 OxF3 Undefined OXF4 Yaniti temizle F ORIG 3500 LEA R3, B LDR R4, R3, #1 NOT RS, R4 ADDR4, R4, #1 STI RS.C JSR F HALT LD ROA AND RI.RO BREZ F RET FILL 20 FILL XIF .FILL 3SOF BLKW3 FILL xFFFF STRINGZ "ABC" FILL 2350D END B D E Which one of the following statements is correct? Yantnz: After instruction "ADD R4, R4, #1" is executed, the value stored in R4 is 1. The execution of instruction "ADD R4, R4, #1" causes an overflow. It is incorrect to use register 4 twice in instruction "ADDR4, R4, #1". The execution of instruction "ADD R4, R4, #1" causes the values in the condition code registers to be set to 1 or 0.
