You are developing a program in Assembly for a PIC$16$F$84$A that generates Pulse Width Modulation output to control a motor. The PWM cycle is $20$ms$.$ The duty cycle should be variable between $1$ms and $19$ms $(5\%$ to $95\%).$

The PWM signal should be produced on PortB pin $1.$

The microcontroller is set to use an $800$ kHz clock.

Timing precision of $\backslash$pm $0\mathrm{.}2$ms is acceptable.

$-$ Create the program in Assembly using MPLAB that sets the correct output at PortB and generates the PWM$.$ The duty cycle could be any value that you insert in your code $($it does not have to be obtained from an external output$).$ The timing should be compatible with the clock frequency.

$-$ Provide a screenshot showing the code and the correct execution.

$-$ Provide a screenshot showing the stopwatch running when the output turns ON and then when it turns OFF $($this should prove that the time between the pulses is $20$ms$)$

Hint: to manage the time you can create a loop that uses $$nop$$ and $$goto$$ for a certain amount of iterations. Recall that every instruction takes $4$ clock cycles and that $$goto$$ takes $2$ instructions while a $$nop$$ and other instructions take $1$ instruction cycle.
