The program

#include< regx51.h> 

void main(void) 
{ 
    unsigned char a,b;  
    P2=0xFFH; $ \ \ \ \ \ \ \  $ //set port 2 as an input  
    P3=0xFFH; $ \ \ \ \ \ \ \  $//set port 1 as an input  
    a=P2; $ \ \ \ \ \ \ \  $ //read status of bits from P2  
    b=P3; $ \ \ \ \ \ \ \  $//read status of bits from P3  
    a=a>>3; $ \ \ \ \ \ \ \  $ //shift P2 bits to right by 3 bits  
    P0=a; $ \ \ \ \ \ \ \  $ //send to port 0  
    b=b>>4; $ \ \ \ \ \ \ \  $ //shift P3 bits to left by 4 bits  
    P1=b; $ \ \ \ \ \ \ \  $ //send to port 1  
}
