Universal Asynchronous Receivers/Transmitters (UARTs)
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.
UART Raw Interrupt Status (UARTRIS)
UART0 base: 0x4000.C000
UART1 base: 0x4000.D000
UART2 base: 0x4000.E000
UART3 base: 0x4000.F000
UART4 base: 0x4001.0000
UART5 base: 0x4001.1000
UART6 base: 0x4001.2000
UART7 base: 0x4001.3000
Offset 0x03C
Type RO, reset 0x0000.0000

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.
9-Bit Mode Raw Interrupt Status
Value Description
0 No interrupt
1 A receive address match has occurred.
This bit is cleared by writing a 1 to the 9BITIC bit in the UARTICR
register.
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
Value Description
0 No interrupt
1 An overrun error has occurred.
This bit is cleared by writing a 1 to the OEIC bit in the UARTICR register.
UART Break Error Raw Interrupt Status
Value Description
0 No interrupt
1 A break error has occurred.
This bit is cleared by writing a 1 to the BEIC bit in the UARTICR register.
