Bits Name Description Type Reset
8 PEIM Parity error interrupt mask. A read returns the current mask
for the UARTPEINTR interrupt. On a write of 1, the mask of
the UARTPEINTR interrupt is set. A write of 0 clears the
mask.
RW 0x0
7 FEIM Framing error interrupt mask. A read returns the current
mask for the UARTFEINTR interrupt. On a write of 1, the
mask of the UARTFEINTR interrupt is set. A write of 0
clears the mask.
RW 0x0
6 RTIM Receive timeout interrupt mask. A read returns the current
mask for the UARTRTINTR interrupt. On a write of 1, the
mask of the UARTRTINTR interrupt is set. A write of 0
clears the mask.
RW 0x0
5 TXIM Transmit interrupt mask. A read returns the current mask
for the UARTTXINTR interrupt. On a write of 1, the mask of
the UARTTXINTR interrupt is set. A write of 0 clears the
mask.
RW 0x0
4 RXIM Receive interrupt mask. A read returns the current mask for
the UARTRXINTR interrupt. On a write of 1, the mask of the
UARTRXINTR interrupt is set. A write of 0 clears the mask.
RW 0x0
3 DSRMIM nUARTDSR modem interrupt mask. A read returns the
current mask for the UARTDSRINTR interrupt. On a write of
1, the mask of the UARTDSRINTR interrupt is set. A write of
0 clears the mask.
RW 0x0
2 DCDMIM nUARTDCD modem interrupt mask. A read returns the
current mask for the UARTDCDINTR interrupt. On a write of
1, the mask of the UARTDCDINTR interrupt is set. A write of
0 clears the mask.
RW 0x0
1 CTSMIM nUARTCTS modem interrupt mask. A read returns the
current mask for the UARTCTSINTR interrupt. On a write of
1, the mask of the UARTCTSINTR interrupt is set. A write of
0 clears the mask.
RW 0x0
0 RIMIM nUARTRI modem interrupt mask. A read returns the current
mask for the UARTRIINTR interrupt. On a write of 1, the
mask of the UARTRIINTR interrupt is set. A write of 0 clears
the mask.
RW 0x0
