Here is my code can someone please help me in changing it to

Here is my code, can someone please help me in changing it to were it can run in one direction continuously, then by pressing the second button it runs in the other direction. CCW to CW. TYIA

#include /* common defines and macros */
#include \"derivative.h\" /* derivative-specific definitions */

//Unipolar stepper motor controller
void delay(int x);
unsigned int IN, OUT;
void main(void)
{
/* put your own code here */
  
DDRC = 0xF0; /*Init PORT C bits 4 - 7 output*/
ATDDIEN = 0x00F0; /*Init bits 4 - 7 PortAD digital inputs*/
PER1AD = 0xF0; /*Enable internal pullups for PAD4 - PAD7*/
  
for(;;)
{
    IN = PT1AD; // Read PortAD;
   if (IN == 0xDF) //Is switch 2 closed (logic 0), rotate motor counter clockwise
   {
       PORTC = 0x80; //CCW
       delay(50); //wait
  
       PORTC = 0x40; //
       delay(50); //wait

       PORTC = 0x20; //
       delay(50); //wait
        PORTC = 0x10; //
       delay(50); //wait
  
   } else if (IN == 0x7F) //Is switch 2 closed (logic 0), rotate motor counter clockwise
   {
       PORTC = 0x10; //CCW
       delay(50); //wait
  
       PORTC = 0x20; //
       delay(50); //wait

       PORTC = 0x40; //
       delay(50); //wait
  
       PORTC = 0x80; //
       delay(50); //wait
   }
   else
PORTC = 0x00; //Turn off MOTOR if button is released (logic 1)
}
}
void delay(int c) //Delay function

int d;
  
for (; c != 0 ; c-- )
for ( d = 1 ; d <= 3270 ; d++ )
