Consider the following ARM assembly program

AREA prog, CODE, READONLY

ENTRY

MOV RO$,$ #$250$

MOV R$1,$ #$1$

repeat ADD R$1,$R$1,$R$0,$ ASR#$3$

TST RO$,$ #$1$

SUBNE RO$,$ # $61$

SUBEQ RO$,$ # $91$

CMP RO$,$ #O

BGT repeat

halt $B$ halt

END

What is the value of R$0$ and R$1$ after executing the above program $($until reaching the $"$B halt" instruction$)?$

$RO=0x$

$,R1=0x$

How many times is the ADD instruction executed?
