Address Detect Transmit

The following procedure is used to transmit in Address Detect mode:

  1. Configure the UART for asynchronous transmit as detailed in Asynchronous Transmit with the MODE[3:0] bits set to ‘0b0100’.
  2. If a Break is desired, write a ‘1’ to SENDB (UxCON[8]).
  3. Write the address value to Parameter 1.
    1. If SENDB = 0, the contents of Parameter 1 will be transmitted with the ninth bit set.
    2. If SENDB = 1, a Break will be transmitted, followed by the contents of Parameter 1 with the ninth bit set.
  4. Write data to be transmitted to the UxTXB register.
