void LcdWdn(unsigned char COM)
{
 unsigned char temp3,temp4;
 LOOP2:DDRT=0xff;
       DDRK=0xff;
       PTT_PTT0=0;
       PTT_PTT1=1;
       PORTK=0xff;
       PTT_PTT2=1;
       DDRK=0x00;
       temp3=PORTK;
       PTT_PTT2=0;
       PTT_PTT2=1;
       PTT_PTT2=0;
       temp3&=0x08;
       if(temp3==0x08)
       goto LOOP2;
       PTT_PTT1=0;
       DDRK=0xff;
       temp4=COM>>4;
       PORTK=temp4;
       PTT_PTT2=1;
       PTT_PTT2=0;
       PORTK=COM;
