Set to 1 SetIEn defines that the marked bits in the InterruptEn Register are set,
Set to 0 clears the marked bits.
Reserved for future use.
Allows the timer interrupt request (indicated by bit TimerIRq) to be propagated to
pin IRQ. This bit can not be set or cleared directly but only by means of bit SetIEn.
Allows the transmitter interrupt request (indicated by bit TxIRq) to be propagated
to pin IRQ. This bit can not be set or cleared directly but only by means of bit
SetIEn.
Allows the receiver interrupt request (indicated by bit RxIRq) to be propagated to
pin IRQ. This bit can not be set or cleared directly but only by means of bit SetIEn.
Allows the idle interrupt request (indicated by bit IdleIRq) to be propagated to pin
IRQ. This bit can not be set or cleared directly but only by means of bit SetIEn.
Allows the high alert interrupt request (indicated by bit HiAlertIRq) to be
propagated to pin IRQ. This bit can not be set or cleared directly but only by
means of bit SetIEn.
Allows the low alert interrupt request (indicated by bit LoAlertIRq) to be
propagated to pin IRQ. This bit can not be set or cleared directly but only by
means of bit SetIEn.
