Hi, I am implementing the J1708 spec. Let me know how to transmit a byte and receive the sane byte back. This is required to get the bus acess for transmission of actaul data.
Hi Gopa,
You can set the Loopback Mode Select bit of UART Mode Control Register, serial data from the transmitter is connected internally to serial input of the receiver, input pin RXD has no effect on loopback and output pin TXD is held in marking state.
