Register Description

Bit #

Name

Descriptions

(nUARTDSR) modem status input. That is , the bit is 1
when the modem status input is 0.

2

RO

DCD

This bit is the complement of the UART data carrier
detect (nUARTDCD) modem status input. That is , the
bit is 1 when the modem status input is 0.

Type

Initial Value

0

3 RO

BUSY

UART

Busy:

If this bit is set to 1, the UART is busy transmitting
data. This bit remains set until the complete byte,
including all the stop bits, has been sent from he shift
register.
This bit is set as soon as the transmit FIFO becomes
non-empty.

0

The meaning of this bit depends on the state of the
FEN bit in the UARTLCR_H register.

RO

0

The meaning of this bit depends on the state of the
FEN bit in the UARTLCR_H register.

RO

TXFE

Transmit FIFO Empty:
The meaning of this bit depends on the state of the
FEN bit in the UARTLCR_H 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.

4

RO

RXFE

Receive FIFO Empty:

If the FIFO is disabled, this bits is set when receive
holding register is empty.
If the FIFO is enabled, the RXFE bit is set when the
receive FIFO is empty.

1

TXFF

Transmit FIFO Full:
The meaning of this bit depends on the state of the
FEN bit in the UARTLCR_H register.
If the FIFO is disabled, this bit is set when transmit
holding register is full.
If the FIFO is enabled, the RXFE bit is set when the
transmit FIFO is full.

6

RO

RXFF

Receive FIFO Full:

If the FIFO is disabled, this bit is set when the receive
holding register is full.
If the FIFO is enabled, the RXFF bit is set when
receive FIFO is full.
