• FRAME:  Framing  Error
0: No stop bit has been detected low since the last RSTSTA. 
1: At least one stop bit has been detected low since the last RSTSTA.
• PARE:  Parity  Error
0: No parity error has been detected since the last RSTSTA.
1: At least one parity error has been detected since the last RSTSTA.
• TIMEOUT:  Receiver  Time-out
0: There has not been a time-out since the last Start Time-out command (STTTO in US_CR) or the Time-out Register is 0.
1: There has been a time-out since the last Start Time-out command (STTTO in US_CR). 
• TXEMPTY:  Transmitter  Empty
0: There are characters in either US_THR or the Transmit Shift Register, or the transmitter is disabled.
1: There are no characters in US_THR, nor in the Transmit Shift Register.
• ITER/UNRE:  Max  number  of  Repetitions  Reached  or  SPI  Underrun  Error
– If USART does not operate in SPI Slave Mode (USART_MODE 
≠ 0xF):
ITER = 0: Maximum number of repetitions has not been reached since the last RSTSTA.
ITER = 1: Maximum number of repetitions has been reached since the last RSTSTA.
– If USART operates in SPI Slave Mode (USART_MODE = 0xF):
UNRE = 0: No SPI underrun error has occurred since the last RSTSTA.
UNRE = 1: At least one SPI underrun error has occurred since the last RSTSTA.
• TXBUFE:  Transmission  Buffer  Empty
0: The signal Buffer Empty from the Transmit PDC channel is inactive.
1: The signal Buffer Empty from the Transmit PDC channel is active.
• RXBUFF:  Reception  Buffer  Full
0: The signal Buffer Full from the Receive PDC channel is inactive.
1: The signal Buffer Full from the Receive PDC channel is active.
• NACK/LINBK  Non  Acknowledge  or  LIN  Break  Sent  or  LIN  Break  Received
– If USART does not operate in LIN Mode (USART_MODE 
≠ 0xA AND ≠ 0xB):
0: No Non Acknowledge has not been detected since the last RSTNACK.
– 1: At least one Non Acknowledge has been detected since the last RSTNACK.If USART operates in LIN Master 
Mode (USART_MODE = 0xA):
0: No LIN Break has been sent since the last RSTSTA.
– 1:At least one LIN Break has been sent since the last RSTSTAIf USART operates in LIN Slave Mode 
(USART_MODE = 0xB):
0: No LIN Break has received sent since the last RSTSTA.
– 1:At least one LIN Break has been received since the last RSTSTA.
LINID:  LIN  Identifier  Sent  or  LIN 
Identifier  Received
If USART operates in LIN Master Mode (USART_MODE = 0xA):
0: No LIN Identifier has been sent since the last RSTSTA.
