UDRE

The UDRE flag indicates if the transmit buffer (UDATA) is ready to be
loaded with new data. If UDRE is ‘1’, it means the transmit buffer is
empty and can hold one or two new data. This flag can generate an
UDRE interrupt. Writing ‘0’ to this bit position will clear UDRE flag.

0

Transmit buffer is not empty.

1

Transmit buffer is empty.

TXC

This flag is set when the entire frame in the transmit shift register has
been  shifted  out  and  there  is  no  new  data  currently  present  in  the
transmit  buffer.  This  flag  is  automatically  cleared  when  the  interrupt
service  routine  of  a  TXC  interrupt  is  executed.  It  is  also  cleared  by
writing ‘0’ to this bit position. This flag can generate a TXC interrupt.

0

Transmission is ongoing.

1

Transmit buffer is empty and the data in transmit shift register
are shifted out completely.

RXC

This flag is set when there are unread data in the receive buffer and
cleared when all the data in the receive buffer are read. The RXC flag
can be used to generate a RXC interrupt.

0

There is no data unread in the receive buffer

1

There are more than 1 data in the receive buffer

WAKE

This flag is set when the RX pin is detected low while the CPU is in
stop mode. This flag can be used to generate a WAKE interrupt. This
bit is set only when in asynchronous mode of operation.

NOTE

0

No WAKE interrupt is generated.

1

WAKE interrupt is generated.

SOFTRST

This is an internal reset and only has effect on USART. Writing ‘1’ to
this bit initializes the internal logic of USART and is auto cleared.

0

No operation

1

Reset USART

DOR

This bit is set if a Data OverRun occurs. While this bit is set, the
incoming data frame is ignored. This flag is valid until the receive buffer
is read.

0

No Data OverRun

1

Data OverRun detected

FE

This bit is set if the first stop bit of next character in the receive buffer
is detected as ‘0’. This bit is valid until the receive buffer is read.

0

No Frame Error

1

Frame Error detected

PE

This bit is set if the next character in the receive buffer has a Parity
Error when received while Parity Checking is enabled. This bit is valid
until the receive buffer is read.

0

No Parity Error

1

Parity Error detected

NOTE:

When the WAKE function of USART is used as a release source from STOP
mode, it is required to clear this bit in the RX interrupt service routine. Else the
device will not wake-up from STOP mode again by the change of RX pin.
