ComIEnReg register bit descriptions
Value
Description
1
signal on pin IRQ is inverted with respect to the Status1Reg register’s
IRq bit
0
signal on pin IRQ is equal to the IRq bit; in combination with the
DivIEnReg register’s IRqPushPull bit, the default value of logic 1 ensures
that the output level on pin IRQ is 3-state
-
allows the transmitter interrupt request (TxIRq bit) to be propagated to
pin IRQ
-
allows the receiver interrupt request (RxIRq bit) to be propagated to pin
IRQ
-
allows the idle interrupt request (IdleIRq bit) to be propagated to pin IRQ
HiAlertIEn
-
allows the high alert interrupt request (HiAlertIRq bit) to be propagated to
pin IRQ
LoAlertIEn -
allows the low alert interrupt request (LoAlertIRq bit) to be propagated to
pin IRQ
ErrIEn
-
allows the error interrupt request (ErrIRq bit) to be propagated to pin IRQ
TimerIEn
-
allows the timer interrupt request (TimerIRq bit) to be propagated to pin
