I am sending 32 bytes from master microcontroller using your I²C library. How can I do that ? Your library handles only single byte of information.
```
////SLAVE CODE DATA READ //
if(!SSPSTATbits.D_nA && !SSPSTATbits.R_nW)
{
  z = SSPBUF;//Address Read
  while(!BF);
  d=SSPBUF;      //data Read
  SSPCONbits.CKP = 1;
  inputflag=1;
}
```

As per standards I²C can send and receive only one byte of information at a time. But you can easily transmit 32 bytes of information serially one after another.
