5) For the provided C-Code below, assume that it will be Compiled and Downloaded to the PIC16F887 Microcontroller. Given Fosc = 20 MHz. Comment all lines of C-Code below marked with comments // and answer the questions that follow: Assume RD0 is Connected to an LED.

Unsigned int ms = 0; //

Void main()

TRISD0 = 0; //

T2CKPS0 = 1; //

T2CKPS1 = 0; //

TOUTPS0 = 0; //

TOUTPS1 = 0; //

TOUTPS2 = 1; //

TOUTPS3 = 0; //

PR2 = 250; //

TMR2ON = 1; //

if(TMR2IF = = 1) //

{

TMR2IF = 0; //

ms++; //

if(ms > = 1000) //

{

ms = 0; //

RD0 = ?RD0; //

}
