The interrupt RXINT for starting the transmission on the responder line always occurs at the mid-point of the commander STOP bit. Depending on the BUSCLK and baud-rate; there might not be enough response space between the STOP bit of commander and START bit of the responder; and the data transmission can start before end of STOP bit.
To overcome this, a delay of half the STOP bit period can be added as response space time to make sure that there is sufficient delay time between STOP and START bit, before start of responder data transmission.
