Register 11: UART Raw Interrupt Status (UARTRIS), offset 0x03C
The UARTRIS register is the raw interrupt status register. On a read, this register gives the current
raw status value of the corresponding interrupt. A write has no effect.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.
UART Overrun Error Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Break Error Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Parity Error Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Framing Error Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Receive Time-Out Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Transmit Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
UART Receive Raw Interrupt Status
Gives the raw interrupt state (prior to masking) of this interrupt.
Software should not rely on the value of a reserved bit. To provide
