12.6.10 Interrupt mask set/clear register, UARTIMSC
The UARTIMSC register is the interrupt mask set/clear register. It is a read/write register.
On a read this register returns the current value of the mask on the relevant interrupt. On
a write of 1 to the particular bit, it sets the corresponding mask of that interrupt. A write of 0
clears the corresponding mask.
All the bits are cleared to 0 when reset. Table 127 lists the register bit assignments.

Bits Name Function
15:11 - RESERVED, read as zero, do not modify.
10 OEIM Overrun error interrupt mask. A read returns the current mask for the UARTOEINTR interrupt.
On a write of 1, the mask of the UARTOEINTR interrupt is set. A write of 0 clears the mask.
9 BEIM Break error interrupt mask. A read returns the current mask for the UARTBEINTR interrupt.
On a write of 1, the mask of the UARTBEINTR interrupt is set. A write of 0 clears the mask.
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.
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.
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.
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.
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.
3DSRMIMnUARTDSR 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.
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.
1CTSMIMnUARTCTS 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.
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.
