DLAB =0. Interrupt Enable Register. Contains individual interrupt enable bits for the 7 potential UART1 interrupts.
| RBRIE | RBR Interrupt Enable. Enables the Receive Data Available interrupt for UART1. It also controls the Character Receive Time-out interrupt. 0 (DISABLE_THE_RDA_INTE): Disable the RDA interrupts. 1 (ENABLE_THE_RDA_INTER): Enable the RDA interrupts. |
| THREIE | THRE Interrupt Enable. Enables the THRE interrupt for UART1. The status of this interrupt can be read from LSR[5]. 0 (DISABLE_THE_THRE_INT): Disable the THRE interrupts. 1 (ENABLE_THE_THRE_INTE): Enable the THRE interrupts. |
| RXIE | RX Line Interrupt Enable. Enables the UART1 RX line status interrupts. The status of this interrupt can be read from LSR[4:1]. 0 (DISABLE_THE_RX_LINE_): Disable the RX line status interrupts. 1 (ENABLE_THE_RX_LINE_S): Enable the RX line status interrupts. |
| MSIE | Modem Status Interrupt Enable. Enables the modem interrupt. The status of this interrupt can be read from MSR[3:0]. 0 (DISABLE_THE_MODEM_IN): Disable the modem interrupt. 1 (ENABLE_THE_MODEM_INT): Enable the modem interrupt. |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
| CTSIE | CTS Interrupt Enable. If auto-cts mode is enabled this bit enables/disables the modem status interrupt generation on a CTS1 signal transition. If auto-cts mode is disabled a CTS1 transition will generate an interrupt if Modem Status Interrupt Enable (IER[3]) is set. In normal operation a CTS1 signal transition will generate a Modem Status Interrupt unless the interrupt has been disabled by clearing the IER[3] bit in the IER register. In auto-cts mode a transition on the CTS1 bit will trigger an interrupt only if both the IER[3] and IER[7] bits are set. 0 (DISABLE_THE_CTS_INTE): Disable the CTS interrupt. 1 (ENABLE_THE_CTS_INTER): Enable the CTS interrupt. |
| ABEOIE | Enables the end of auto-baud interrupt. 0 (DISABLE_END_OF_AUTO_): Disable end of auto-baud Interrupt. 1 (ENABLE_END_OF_AUTO_B): Enable end of auto-baud Interrupt. |
| ABTOIE | Enables the auto-baud time-out interrupt. 0 (DISABLE_AUTO_BAUD_TI): Disable auto-baud time-out Interrupt. 1 (ENABLE_AUTO_BAUD_TIM): Enable auto-baud time-out Interrupt. |
| RESERVED | Reserved, user software should not write ones to reserved bits. The value read from a reserved bit is not defined. |
