The idea is to display the value of TMR$0$ of PIC$16$F$877$A in decimal format on $2$ seven segment displays.

$1.$ Connect two push buttons to the PIC: push$\_$button$\_0$ to the RA$4/$TOCKI pin. push$\_$button$\_1$ to any other pin.

$2.$ Connect two common anode $7-$segment displays to the PIC; to displays the value of TMRO, in decimal format, $($TMRO will count, continuously, from $00$ to $99).$

$3.$ Each time push$\_$button$\_0$ is pressed; TMRO register is incremented by $1.$

$4.$ Each time push$\_$button$\_1$ is pressed, TMRO register must be cleared.

Use MPLAB to generate the hex file.

Simulate your work using Proteus.

Use PIC$16$F$877$A
