UART
10-10
31
[0] Overrun error (OV)
0 = No overrun error during receive
1 = Overrun error (generate receive status interrupt if UCON[2] is 1)
[1] Parity error (PE)
0 = No parity error during receive
1 = Parity error (generate receive status interrupt if UCON[2] is 1)
[2] Frame error (FE)
0 = No frame error during receive
1 = Frame error (generate receive status interrupt if UCON[2] is 1)
[3] Break detect (BKD)
0 = No break received
1 = Break received (generate receive stauts interrupt if UCON[2] is 1)
[4] Data terminal ready (DTR)
0 = DTR pin (nUADTR) is High
1 = DTR pin (nUADTR) is Low
[5] Receive data ready (RDR)
0 = No vaild data in the receive buffer register
1 = Vaild data present in the receive buffer register
[6] Transmit buffer register empty (TBE)
0 = Vaild data in transmit holding register
1 = No data in transmit holdign register
[7] Transmit complete (TC)
0 = Transmit in progress
1 = Transmit complete; no data for Tx
(issue interrupt or DMa request if UCON[1:0] is set)
(as the setting of UCON[4:3], interrupt or GDMA request is generated)
