The hal$\_$entry.c file should be like the following code

$*$ Port Control Register $1$ on P$451$ of S$7$G$2$ databook $*/$

#define P$6$PCNTR$1(*($volatile unsigned long $*)0$x$400400$C$0)$

while $(1)\{$

$**$ W$4400400$C$0,00000001,$ turn on the green LED $*/$

for $($int i$=0$; i$<mn>1</mn><mn>0</mn><mn>0</mn><mn>0</mn><mn>0</mn><mn>0</mn><mn>0</mn>$; i$++)$ P$6$PCNTR$1=0$x$00000001$;$\}$

Build the project again and download the machine code to the microcontroller board. Is the green LED

blinking after the program is executed? Use an oscilloscope to measure signal P$600$ and attach a hardcopy

of the signal here. How long does the green LED keep on $($measure the duration for the low voltage$)?$ How

long does the green LED keep off $($measure the duration of the high voltage$)?$ Can a human being react to

this change?
