RXRIS
Receive Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTRXINTR interrupt.
0: indicates UARTRXINTR interrupt is unmasked, enabled.
1: indicates UARTRXINTR interrupt is masked, disabled.
TXRIS
Transmit Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTTXINTR interrupt.
RTRIS
Receive Timeout Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTRTINTR interrupt.
FERIS
Framing Error Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTFEINTR interrupt.
PERIS
Parity Error Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTPEINTR interrupt.
BERIS
Break Error Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTBEINTR interrupt.
OERIS
Overrun Error Interrupt Status Bit
Gives the raw interrupt state (prior to masking) of the UARTOEINTR interrupt.
NOTE
In this case the raw interrupt cannot be set unless the mask is set, this is because the mask acts as an
enable for power saving. That is, the same status can be read from UARTMIS and ARTRIS for the receive
timeout interrupt.
