TXFE
R
When UARTxLCR_H<FEN> = "1"
0: The transmit FIFO is not empty.
1: The transmit FIFO is empty.
When UARTxLCR_H<FEN> = "0"
0: The transmit hold register is not empty.
1: The transmit hold register is empty.
6
RXFF
R
When UARTxLCR_H<FEN> = "1"
0: The receive FIFO is not full.
1: The receive FIFO is full.
When UARTxLCR_H<FEN> = "0"
0: The receive hold register is not full.
1: The receive hold register is full.
5
TXFF
R
When UARTxLCR_H<FEN> = "1"
0: The transmit FIFO is not full.
1: The transmit FIFO is full.
When UARTxLCR_H<FEN> = "0"
0: The transmit hold register is not full.
1: The transmit hold register is full.
4
RXFE
R
When UARTxLCR_H<FEN> = "1"
0: The receive FIFO is not empty.
1: The receive FIFO is empty.
When UARTxLCR_H<FEN> = "0"
0: The receive hold register is not empty.
1: The receive hold register is empty.
3
BUSY
R
UART busy
0: UART transmission is stopping.
1: UART transmission is ongoing.
This bit is set to "1" when the transmit FIFO is not empty regardless of whether UART operation is ena-
bled or not.
