1: At least one change has been detected on the DCD pin since the last CSR read.
0: No change has been detected on the DSR pin since the last CSR read.
1: At least one change has been detected on the DSR pin since the last CSR read.
0: No change has been detected on the RI pin since the last CSR read.
1: At least one change has been detected on the RI pin since the last CSR read.
0: The USART is either idle or a LIN transfer is ongoing.
1: A LIN transfer has been completed since the last RSTSTA.
0: No LIN Identifier has been sent or received.
1: A LIN Identifier has been sent (master) or received (slave), since the last RSTSTA.
0: No Non Acknowledge has been detected since the last RSTNACK.
1: At least one Non Acknowledge has been detected since the last RSTNACK.
0: The Buffer Full signal from the Peripheral DMA Controller channel is inactive.
1: The Buffer Full signal from the Peripheral DMA Controller channel is active.
If USART does not operate in SPI Slave Mode:
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:
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.
0: The transmitter is either disabled or there are characters in THR, or in the transmit shift register.
1: There are no characters in neither THR, nor in the transmit shift register.
0: There has not been a time-out since the last Start Time-out command (CR.STTTO), or RTOR.TO is zero.
1: There has been a time-out since the last Start Time-out command.
0: Either no parity error has been detected, or the parity bit is a zero in multidrop mode, since the last RSTSTA.
1: Either at least one parity error has been detected, or the parity bit is a one in multidrop mode, since the last RSTSTA.
0: No stop bit has been found as low since the last RSTSTA.
1: At least one stop bit has been found as low since the last RSTSTA.
