Study the following code (you can assume ". . ." refers to code that is not shown) main: LDI R27, hi8(d1) ; PC = 0x0A35, SP = 0x0B17 LDI R26, lo8(d1) LD R18, X+ ADD R18, R18 PUSH R0 CALL subroutine1 POP R18 ; What is the value of the SP after completion of this line of code? ... subroutine1: POP R18 ... RET You can assume that the address of subroutine1 is 0x1A19 and that this code was generated by the AVR-GCC compiler and follows the relevant conventions What is the value of the Stack Pointer at the highlighted line of code? (Write your answer in Decimal)
