1.4.2 Asynchronous 9-bit UART Address Mode Address Mismatch
In Asynchronous 9-bit UART Address mode there is the possibility that a false address mismatch may occur even when the address of both devices match, or that a false address match may occur when there is an address mismatch between the devices.
Work around
None. Do not use the UART modules in Asynchronous 9-bit Address Mode
