PLEASE DO THIS HOMEWORK FOR ME AND ANSWER EVERYTHING!!!! Below is the SystemInit Function in our system$\_$stm$32$f$4$xx$.$c file: #endif $/*$ Reset the RCC clock configuration to the default reset state $/*$ Set HSION bit $*/$ RCC$->$CR I$=($uint$32\_$t$)0$x$00000001$; $/*$ Reset CFGR register $*/$ RCC$->$CFGR $=0$x$00000000$; $/*$ Reset HSEON, CSSON and PLLON bits $*/$ RCC$->$CR &$=($uint$32\_$t$)0$xFEF$6$FFFF; $/*$ Reset PLLCFGR register $*/$ RCC$->$PLLCFGR $=0\backslash$times$24003010$; $/*$ Reset HSEBYP bit $*/$ RCC$->$CR &$=($uint$32\_$t$)0$xFFFBFFFF; $/*$ Disable all interrupts $*/$ RCC$->$CIR $=0$x$00000000$;$]$#if defined $($DATA$\_$IN$\_$ExtSRAM$)$ Il defined $($DATA$\_$IN$\_$ExtSDRAM$)$ SystemInit$\_$ExtMemC$-$rl$()$;#endif $/*$ DATMA$\_$IN$\_$ExtSRAM $|$ DATA$\_$IN$\_$ExtSDRAM $*//*$ Configure the Vector Table location add offset address $------------------------/]*$ifdef VECT$\_$TAB$\_$SRAM SCB$->$VTOR $=$ SRAM$\_$BASE $|$ VECT$\_$TAB$\_$OFFSET; $/*$ Vector Table Relocation in Internal SRAM $*/$ #else SCB$->$VTOR $=$ FLASH$\_$BASE $|$ VECT$\_$TAB$\_$OFFSET; $/*$ Vector Table Relocation in Internal FLASH $*/$ #endif$|$

Consider the following FIVE lines in the SystemInit$()$ function above

$RCCCR$ I $=(uint{32}_t)0x00000001$;

$RCCCFGR=0x00000000$;

$RCCCR\frac{?}{?}$& $=(uint{32}_t)0$xFEF$6FFFF$;

$RCCPLLCFGR=0x24003010$;

$RCCCR\frac{?}{?}$& $=(uint{32}_t)0xFFFBFFFF$;

These five lines are configuring the clock. For each line, briefly explain what is happening by referring to Chapter $7$ in the STM$32$F$407$ Reference Manual $($RM$0090).$

What is the SYSTEM CLOCK SYSCLK when these $5$ lines are executed?
