If there is no error, it will hold the value zero. This register will not be updated by subsequent errors arriving in the DMA. The next error will only be recorded if the buffer unloads and is reloaded or the receive DMA is reset. 15 0-R 14 0-RW 13 0-RW 12 0-RW 11 0-RW 10 0-RW 9 0-RW 8 0-RW 0 INT_ SC1PARERR INT_ SC1FRMERR INT_ SCTXULDB INT_ SCTXULDA INT_ SCRXULDB INT_ SCRXULDA INT_SCNAK INT_ SCCMDFIN INT_ SCTXFIN INT_ SCRXFIN INT_ SCTXUND INT_ SCRXOVF INT_ SCTXIDLE INT_ SCTXFREE INT_ SCRXVAL 0-RW 7 0-RW 6 0-RW 5 0-RW 4 0-RW 3 0-RW 2 0-RW 1 0-RW 0 INT_SC1PARERR [14] Parity error received (UART) interrupt enable.
