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.
