Question: ( 1 ) Show the stack content immediately before the PUSH instruction runs. Suppose the stack pointer SP ( i . e . , MSP

(1) Show the stack content immediately before the PUSH instruction runs. Suppose the stack pointer SP (i.e., MSP in this case) is \(0\times 2000\_0600\) immediately before the system timer interrupt occurs.
```
SysTick_Handler PROC
PUSH {r4, r5, r6}
ADD r0, r0, #1
ADD r1, r1, #1
ADD r2, r2, #1
ADD r3, r3, #1
ADD r4, r4, #1
ADD r5, r5, #1
ADD r6, r6, #1
ADD r7, r7, #1
ADD r8, r8, #1
ADD r9, r9, #1
ADD r10, r10, #1
ADD r11, r11, #1
ADD r12, r12, #1
POP {r4, r5, r6}
BX LR
ENDP
```
