Rev. 3.2 — 12 January 2010
signal on pin IRQ is inverted with respect to the Status1Reg register’s IRq
bit
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
allows the high alert interrupt request (HiAlertIRq bit) to be propagated to
pin IRQ
allows the low alert interrupt request (LoAlertIRq bit) to be propagated to
pin IRQ
allows the error interrupt request (ErrIRq bit) to be propagated to pin IRQ
allows the timer interrupt request (TimerIRq bit) to be propagated to pin
IRQ
RxIRq
pin IRQ is a standard CMOS output pin
pin IRQ is an open-drain output pin
reserved for future use
allows the MFIN active interrupt request to be propagated to
pin IRQ
reserved for future use
allows the CRC interrupt request, indicated by the DivIrqReg
register’s CRCIRq bit, to be propagated to pin IRQ
reserved for future use
