Bit Name
Enable Modem Status Interrupt Mask Status.
If set (interrupt unmasked), the UART_IMSK.EDSSI bit indicates enabling of a mo-
dem status interrupt request on the same status interrupt channel when the
UART_STAT.SCTS bit is set. This indicates UART_CTS pin re-assertion. Write-1-
to-clear (W1C) the UART_STAT.SCTS bit to clear the interrupt request.
Enable Line Status Interrupt Mask Status.
If set (interrupt unmasked), the UART_IMSK.ELSI bit indicates that redirection of
TX and RX interrupt requests to the status interrupt output of the UART by OR'ing
them with the UART_STAT.OE, UART_STAT.PE, UART_STAT.FE, and
UART_STAT.BI interrupt requests. Set this bit when no DMA channel is associated
with the UART. Enabling UART_IMSK.ELSI disables the RX/TX interrupt chan-
nels and negates the UART_IMSK.EDTPTI bit.
Enable Transmit Buffer Empty Interrupt Mask Status.
If set (interrupt unmasked), the UART_IMSK.ETBEI bit indicates generation of a
TX interrupt request if the UART_STAT.THRE bit is set.
Enable Receive Buffer Full Interrupt Mask Status.
If set (interrupt unmasked), the UART_IMSK.ERBFI indicates generation of an RX
interrupt request if the UART_STAT.DR bit is set.
