17.4 Protocol Extensions

The UART provides hardware support for LIN/J2602, DMX and smart card protocol extensions to reduce software overhead. A protocol extension is enabled by writing a value to the MOD[3:0] (UxMODE[3:0]) selection bits and further configured using the UARTx Timing Parameter registers, UxP1, UxP2, UxP3 and UxP3H. Details regarding operation and usage are discussed in their respective chapters. Not all protocols are available on all devices.
