Access:
• RXRDY: Receiver Ready
0 = No character has been received since the last read of the UART_RHR or the receiver is disabled.
1 = At least one complete character has been received, transferred to UART_RHR and not yet read.
• TXRDY: Transmitter Ready
0 = A character has been written to UART_THR and not yet transferred to the Shift Register, or the transmitter is disabled.
1 = There is no character written to UART_THR not yet transferred to the Shift Register.
• ENDRX: End of Receiver Transfer
0 = The End of Transfer signal from the receiver Peripheral Data Controller channel is inactive.
1 = The End of Transfer signal from the receiver Peripheral Data Controller channel is active.
• ENDTX: End of Transmitter Transfer
0 = The End of Transfer signal from the transmitter Peripheral Data Controller channel is inactive.
1 = The End of Transfer signal from the transmitter Peripheral Data Controller channel is active.
• OVRE: Overrun Error
0 = No overrun error has occurred since the last RSTSTA.
1 = At least one overrun error has occurred since the last RSTSTA.
• FRAME: Framing Error
0 = No framing error has occurred since the last RSTSTA.
1 = At least one framing error has occurred since the last RSTSTA.
• PARE: Parity Error
0 = No parity error has occurred since the last RSTSTA.
