UART S3F401F_UM_REV1.00
12-18
NOTES:
1. The received data character must be read first from UARTDR before reading the error status associated with that data
character from UARTRSR. This read sequence cannot be reversed, because the status register UARTRSR is updated
only when a read occurs from the data register UARTDR. However, the status information can also be obtained by
reading the UARTDR register.
2. These bits (UERSATn[3:0]) are automatically cleared to 0 when the UART error status register is read.
