Parameter 3 Most Significant bit

UART mode operating parameter values
ValueNameDescription
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

Parameter 3 Least Significant bits

UART mode operating parameter values
ValueNameDescription
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
