Preliminary
Description
Reserved bits return an indeterminate value, and should never
be changed.
UART Transmit FIFO Empty
The meaning of this bit depends on the state of the FEN bit in the
UARTLCRH register.
If the FIFO is disabled (FEN is 0), this bit is set when the transmit
holding register is empty.
If the FIFO is enabled (FEN is 1), this bit is set when the transmit
FIFO is empty.
UART Receive FIFO Full
The meaning of this bit depends on the state of the FEN bit in the
UARTLCRH register.
If the FIFO is disabled, this bit is set when the receive holding
register is full.
If the FIFO is enabled, this bit is set when the receive FIFO is
full.
UART Transmit FIFO Full
The meaning of this bit depends on the state of the FEN bit in the
UARTLCRH register.
If the FIFO is disabled, this bit is set when the transmit holding
register is full.
If the FIFO is enabled, this bit is set when the transmit FIFO is
full.
