Bit 8 – P3[8] Parameter 3 Most Significant bit

UART mode operating parameter values

Value	Name	Description
n	MODE = DMX	Most Significant bit of last address of receive block
x	All other modes/Limited featured UART	Not used

Bits 7:0 – P3[7:0] Parameter 3 Least Significant bits

UART mode operating parameter values

Value	Name	Description
n	MODE = DMX	Least Significant bits of last address of receive block
n	MODE = LIN Client	Number of data bytes to receive
n	MODE = Asynchronous Address	Receiver address mask. Received address is XOR’d with UxP2L, then AND’d with UxP3L. Match occurs when result is zero.
x	All other modes	Not used
