J$-$Link Lab $2$ and $3$

C Program

Review Lab $2$ and $3$ to finish the following questions about using $"$w$4$ and mem$32"$ commands:

Which register is used to configure port $0$ as an input port? What is the address of this register? Register: and its address is $$

Which register is used to read port $0$ data into microprocessor? What is the address of this register? Register and its address is $$

Which register is used to configure port $6$ as an output port? What is the address of this register? Register: and its address is $$

Use J$-$Link $"$w$4"$ command to configure port $0$ as an input port:

$$

Use J$-$Link $"$w$4"$ command to configure port $6$ as an output port:

$$

Use J$-$Link "mem$32"$ command to read data from port $0$ into microprocessor: $$

Use bitwise operation to get bit $6$ of port $0$ in order to see whether $54$ are pressed or not.

If bit $6$ is $0,S4$ is pressed $($ P $12$ in SK$-$S$7$G$2$ schematic$)$ and turn on the green LED connected to P$600,$ e$.$g$.$ reset P$600,$ PODR$00=0..$ If $54$ is releases, turn off green LED.

Use J$-$Link $"4"$ command to turn on the green LED connected to P$600.$

Use J$-$Link $"$w$4"$ command to turn off the green LED connected to P$600$

If $($POdata $==0)$

$/*=P0CTR1=0x00000000$;

$P6CTR1=0x0000FFFF$;

$\frac{?}{?}*=to$ read $in$ data from port$\frac{*}{}$

Unsigned long $P0$data $=P0CTR2$;

$\frac{?}{?}*$ Using logic calculation $to$ get bit $6$ value$\frac{*}{}$

$P0$data $=P0$data $\frac{?}{?}$& $0x00000060$; $\frac{?}{?}*if$ bit $6=0,54is$ pressed, and

POdata $=0\frac{*}{}\frac{?}{*}$

$=$ write data $to$ LED$\frac{*}{P}6CTR1=0x0007FFFF$;
