Errata Descriptions
1.
UART/Reception in Modes 1, 2 and 3/UART False Start Bits Detection
When a false start bit occurs on the UART, some UART internal signals are not reset.
Then when a real start bit occurs, the sampling is shifted.
Workaround
None.
2.
During UART Reception, Clearing REN May Generate Unexpected IT
During UART reception, if the REN bit is clear between a start bit detection and the
end of reception, the UART will not discard the data (RI is set).
Workaround
Test REN at the beginning of Interrupt routine just after CLR RI, and run the Interrupt
routine code only if REN is set.
