Here is working code:
Enjoy...


//Encode a byte to Manchester code
long enman(int this){
long man;
int i,lob,hib;
#bit tbit=this.0
lob=man;
for(i=0;i<4;i++){
shift_right(&lob,1,tbit);
shift_right(&lob,1,!tbit);
rotate_right(&this,1);
}
hib=hi(man);
for(i=0;i<4;i++){
shift_right(&hib,1,tbit);
shift_right(&hib,1,!tbit);
rotate_right(&this,1);
}
man=lob;
hi(man)=hib;
return(man);
}

//Decode Manchester code to original byte
int decman(long this){
int i,temp,out;
#bit tbit=temp.0
temp=this;
out=0;
for(i=0;i<4;i++){
shift_right(&out,1,tbit);
rotate_right(&temp,1);
rotate_right(&temp,1);
}
temp=hi(this);
for(i=0;i<4;i++){
shift_right(&out,1,tbit);
rotate_right(&temp,1);
rotate_right(&temp,1);
}
return(out);
}
