COS
Change-of-state.
0 UIPCRn[COS] is not selected.
1 Change-of-state occurred on CTS and was programmed in UACRn[IEC] to cause an interrupt.
Autobaud calculation.
0 Autobaud is disabled or is waiting for the first receiver character.
1 The baud rate has been calculated and loaded into the clock source divider (UDUn and UDLn).
After being set, this bit is cleared by writing to UCRn[ENAB].
Receiver FIFO status. After being set, this bit is cleared by reading URBn.
0 FIFO status indication is disabled or the receiver status has not changed.
1 The receiver status has changed as programmed in URFn[RXS].
Transmitter FIFO status. After being set, this bit is cleared by writing UTBn.
0 FIFO status indication is disabled or the transmitter status has not changed.
1 The transmitter status has changed as programmed in UTFn[TXS].
Receiver FIFO timeout.
0 No receiver FIFO timeout. This bit is cleared by reading all remaining data in the receiver FIFO, by
1 The receiver FIFO has timed out at 64 baud with unread data below the FIFO fullness level.
Delta break.
0 No new break-change condition to report.
1 The receiver detected the beginning or end of a received break.
RxRDY (receiver ready) if UMR1n[FFULL/RxRDY] = 0; FIFO full (FFULL) if UMR1n[FFULL/RxRDY] = 1.
Duplicate of USRn[FFULL/RxRDY].
Transmitter ready. This bit is the duplication of USRn[TxRDY].
0 The transmitter holding register was loaded by the CPU or the transmitter is disabled. Characters loaded
