Func
the subroutine Func given in Chapter 2 of your E-Book:
MOV R1,#100; R1=100
MUL RO, RO,R1 ; R0=100*input
ADD R0,#10 ; R0=100*input+10
BX LR ; return 100*input+10
If we wanted to pass the decimal number 34 to this subroutine (function) we would
a. MOV R1, #34 then B Func
b. MOV R1, #34 then BL Func
c. MOV RO, #34 then BL Func
