What is the significance of the contents of the memory location at 0x0000.0004?

Upon power-on RESET, what is the address location that the ARM Cortes-M4 starts execution from?

Case (d): DIV400 = 0, Processor Clock = 5 MHz

Place your codes for PLL initialization & submit screenshoot of 'SystemCoreClock'.

Note: 

 - Text are limited to 40 lines max. You can submit the portions of the code that was modified.

 - Save your screenshot in a file and attach to your response.

Case (c): DIV400 = 0, Processor Clock = 20 MHz

Place your codes for PLL initialization & submit screenshoot of 'SystemCoreClock'.

Record the value of your program's Stack Pointer (R13) when your program halts at the breakpoint 1 (refer to Lab 2, slide 12) within the SysTick handler. This is the value of your Stack pointer after stacking.

Write your answer in the format 0xnnnn.nnnn, e.g. 0x2000.02E0.

What is the processor mode when your program is within the SysTick Handler?

What is the interrupt (ISR) number for the SysTick timer?

How many bytes are pushed to the stack during a function call?

Write your answer in decimal.

Record the value of your program's Stack Pointer (R13) before your program runs (refer to Lab 2, slide 11). This is the initial value of your program's Stack pointer.

Write your answer in the format 0xnnnn.nnnn, e.g. 0x2000.02E0.

Case (b): DIV400 = 1, Processor Clock = 10 MHz

Place your codes for PLL initialization & submit screenshoot of 'SystemCoreClock.

Note: 

 - Text are limited to 40 lines max. You can submit the portions of the code that was modified.

 - Save your screenshot in a file and attach to your response.
