AREA .text, CODE, READONLY, ALIGN=2 GET tm4c123gh6pm. 3 EXPORT Start OOC Jan WN PP Start MOV RO, #0x80; MOV Ri, #Ox1; BL Logic B Stop 12 Stop 13 14 Logic 25 ORR R2, RO, R1; BX LR After executing instruction in Line 14, the value of R14 is: the address of instruction in Line 10 the address of instruction in Line 12 the address of instruction in Line 14 the address of instruction in Line 15

Answer 1

In ARM the R14 is also called LR (Link Register)

It stores the return address when a function call is made. The return address is the address of the next instruction after the function call

The function call is made at line 10, and the next instruction is at line 12.

So R14 contains the instruction in Line 12

So option 2 is correct
