Description
UART Transmit Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the TXRIS
bit in the UARTRIS register is set.
0 The TXRIS interrupt is suppressed and not sent to the interrupt
controller.
0
UART Receive Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the RXRIS
bit in the UARTRIS register is set.
0 The RXRIS interrupt is suppressed and not sent to the interrupt
controller.
0
UART Data Set Ready Modem Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the DSRRIS
bit in the UARTRIS register is set.
0 The DSRRIS interrupt is suppressed and not sent to the interrupt
controller.
This bit is implemented only on UART1 and is reserved for UART0 and
UART2.
0
UART Data Carrier Detect Modem Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the DCDRIS
bit in the UARTRIS register is set.
0 The DCDRIS interrupt is suppressed and not sent to the interrupt
controller.
This bit is implemented only on UART1 and is reserved for UART0 and
UART2.
0
UART Clear to Send Modem Interrupt Mask
Value Description
1 An interrupt is sent to the interrupt controller when the CTSRIS
bit in the UARTRIS register is set.
0 The CTSRIS interrupt is suppressed and not sent to the interrupt
controller.
This bit is implemented only on UART1 and is reserved for UART0 and
UART2.
