Consider the following complete LC$-3$ program with $3$ bugs $(2$ syntax and $1$ logie$)$:

START $3000$

SUM ID RO$,$ ZERO

LD RT$,N$

NOT R$1,$ R$1$

ADB R$1,$ RT$,*1$

LD R$2,$ ZERO

LOOP ADD R$3,$ R$1,$ R$2$

BR$2$DONE

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

ADB R$2,$ R$2,$ #$1$

BRnzp LOOP

DONE STO RO$,$TOTAL

HALT

$N.$FILL $x000B$

ZERO FILL XFFFF

TOTAL BLKW #$1$

END

The program is meant to sum the integers from zero up to but not including $N$ and se the total in memory.

Identify the bugs in the program above. FYI: Be certain: Canvas deducts points fo 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
