IRQ Enable Register (IRQEn)
The IRQEn register is used to enable the IRQ physical interrupt. Any of the eight ISR interrupt sources can be enabled
to generate an interrupt on IRQ. The IRQEn bits only influence the IRQ output and do not have any effect on the ISR
contents or behavior. Every one of the IRQEn bits operates on a corresponding ISR bit.
Bit 7: CTSIEn
The CTSIEn bit enables IRQ interrupt generation when the CTSInt interrupt is set in ISR[7]. Set CTSIEn low to disable
IRQ generation from CTSInt.
Bit 6: RxEmtyIEn
The RxEmtyIEn bit enables IRQ interrupt generation when the RxEmptyInt interrupt is set in ISR[6]. Set RxEmtyIEn low
to disable IRQ generation from RxEmptyInt.
Bit 5: TFifoEmtyIEn
The TFifoEmtyIEn bit enables IRQ interrupt generation when the TFifoEmptyInt interrupt is set in ISR[5]. Set TFifoEmtyIEn
low to disable IRQ generation from TFifoEmptyInt.
Bit 4: TxTrgIEn
The TxTrgIEn bit enables IRQ interrupt generation when the TxTrigInt interrupt is set in ISR[4]. Set TxTrgIEn low to
disable IRQ generation from TxTrigInt.
Bit 3: RxTrgIEn
The RxTrgIEn bit enables IRQ interrupt generation when the RxTrigInt interrupt is set in ISR[3]. Set RxTrgIEn low to
disable IRQ generation from RxTrigInt.
Bit 2: STSIEn
The STSIEn bit enables IRQ interrupt generation when the STSInt interrupt is set in ISR[2]. Set STSIEn low to disable
IRQ generation from STSInt.
Bit 1: SpChrIEn
The SpChrIEn bit enables IRQ interrupt generation when the SpCharInt interrupt is set in ISR[1]. Set SpChrIEn low to
disable IRQ generation from SpCharInt.
Bit 0: LSRErrIEn
The LSRErrIEn bit enables IRQ interrupt generation when the LSRErrInt interrupt is set in ISR[0]. Set LSRErrIEn low to
disable IRQ generation from LSRErrInt.
