Programmable Registers
30.4.8 UART Status Register (HW_UARTAPP_STAT)
The UART Status Register contains the various flags and receive status. If the status is read
from this register, then the status information for break, framing and parity corresponds to
the data character read from the UART Data Register prior to reading the UART Status
Register. The status information for overrun is set immediately when an overrun condition
occurs.

This read-only bit indicates that the Application UART function is present when it reads back a one. This
Application UART function is not available on a device that returns a zero for this bit field.

Transmit FIFO Empty. The meaning of this bit depends on the state of the FEN bit in the UART Line Control
Register. If the FIFO is disabled, this bit is set when the transmit holding register is empty. If the FIFO is
enabled, the TXFE bit is set when the transmit FIFO is empty.
