Transmission complete

Noise flag
Framing error
This bit is set by hardware when transmission of a frame containing data is complete.
An interrupt is generated if TCIE = 1 in the SCICR2 register. It is cleared by a
software sequence (an access to the SCISR register followed by a write to the
SCIDR register).
0: Transmission is not complete
1: Transmission is complete
Note: TC is not set after the transmission of a Preamble or a Break.
This bit is set by hardware when the content of the RDR register has been
transferred to the SCIDR register. An interrupt is generated if RIE = 1 in the SCICR2
register. It is cleared by a software sequence (an access to the SCISR register
followed by a read to the SCIDR register).
0: Data is not received
1: Received data is ready to be read
This bit is set by hardware when a Idle Line is detected. An interrupt is generated if
the ILIE = 1 in the SCICR2 register. It is cleared by a software sequence (an access
to the SCISR register followed by a read to the SCIDR register).
0: No idle line is detected
1: Idle line is detected
Note: The IDLE bit is not reset until the RDRF bit has itself been set (that is, a new
idle line occurs).
This bit is set by hardware when the word currently being received in the shift register
is ready to be transferred into the RDR register while RDRF = 1. An interrupt is
generated if RIE = 1 in the SCICR2 register. It is cleared by a software sequence (an
access to the SCISR register followed by a read to the SCIDR register).
0: No overrun error
1: Overrun error is detected
Note: When this bit is set RDR register content is not lost but the shift register is
overwritten.
This bit is set by hardware when noise is detected on a received frame. It is cleared
by a software sequence (an access to the SCISR register followed by a read to the
SCIDR register).
0: No noise is detected
1: Noise is detected
Note: This bit does not generate interrupt as it appears at the same time as the
RDRF bit which itself generates an interrupt.
This bit is set by hardware when a desynchronization, excessive noise or a break
character is detected. It is cleared by a software sequence (an access to the SCISR
register followed by a read to the SCIDR register).
0: No framing error is detected
1: Framing error or break character is detected
Note: This bit does not generate interrupt as it appears at the same time as the
RDRF bit which itself generates an interrupt. If the word currently being transferred
causes both Frame Error and Overrun error, it is transferred and only the OR bit will
be set.
