Register 12: UART Masked Interrupt Status (UARTMIS), offset 0x040
The UARTMIS register is the masked interrupt status register. On a read, this register gives the
current masked status value of the corresponding interrupt. A write has no effect.
UART Masked Interrupt Status (UARTMIS)
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 0x040

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.
Transmit DMA Masked Interrupt Status
Value Description
0 An interrupt has not occurred or is masked.
1 An unmasked interrupt was signaled due to the completion of
the transmit DMA.
This bit is cleared by writing a 1 to the DMATXIC bit in the UARTICR
register.
Receive DMA Masked Interrupt Status
Value Description
0 An interrupt has not occurred or is masked.
1 An unmasked interrupt was signaled due to the completion of
the receive DMA.
This bit is cleared by writing a 1 to the DMARXIC 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.
