6. (5 points) Suppose register i (i≤12) is initialized to have a value of i (e.g. r0-0, r1-1,2-2,13- 3, etc.). Assumes the main stack (MSP) stack is used. In addition, in the interrupt handler, if LR- OxFFFFFFF9, then the main stack (MSP) is used. If LR- 0xFFFFFFFD, then the Process Stack (PSP) is used. When the interrupt occurs, the program status register (PSR)-0x00000020, PC-0x08000020, LR -0x08000180, SP-0x20001000.
