Consider the following complete LC$-3$ program with $3$ bugs $(2$ syntax and $10$ ogio:

SUM START $3000$

SUM LD RO$,$ ZERO

LD RL$.N$

NOT RL RT

ADD RL RL$,41$

LD R$2,$ ZERO

LOOP ADD R$3.$ RL$.$ R$2$

BR$2$DONE

ADD RO$,$ RO$,$ R$2$

ADD R$2,$R$2,$ A$1$

BRnzp LOOP

DONE STO RO$.$ TOUAL

HALT

$w$ FLL $x000B$

ZERO FILL XFFFF

TOTAL BLKN

END

The program is meant to sum the integers from zero up to but not including N and save the total in memory. Identify the bugs in the program above. FYI: Be certain; Canvas deducts points for incorrect choices.

register not properly initialized

invalid operation$/$opcode

wrong order of operand types

wrong instruction sets condition codes prior to branch

incorrect branch NZP bits

undefined$/$invalid label

memory not properly initialized

invalid assembler directive

wrong number of operands

invalid register name
