[3] OE – Overrun error
This bit is set to 1 if data is received and the FIFO is already full.
This bit is cleared to 0 by a write to UART0ECR
[2] BE – Break error
This bit is cleared to 0 by a write to UART0ECR
[1] PE – Parity error
When set to 1, it indicates that the parity of the received data character does not
match
the parity that the EPS and SPS bits in the line control register, UARTLCR_H select
This bit is cleared to 0 by a write to UART0ECR
[0] FE – Framing error
When set to 1, in indicates that the received character didn’t have a valid stop bit
This bit is cleared to 0 by a write to UART0ECR
UART0FR (UART0 Flag Register)
Address offset: 0x0018
Reset value: 0bx11000xxx

[8] RI – Ring indicator
This bit is the complement of the UART ring indicator, UART0RI.
1: When nUART0RI is LOW
[7] TXFE – Transmit FIFO empty
This bit depends on the state of the FEN bit in the line control register, UARTLCR_H.
0: The bit is set when transmit holding register is empty.
1: The bit is set when transmit FIFO is empty
