Description

Set

1: writing a 1 to a bit position 5..0 sets the interrupt request

0: Writing a 1 to a bit position 5..0 clears the interrupt request

GlobalIrq

Set, if an enabled Irq occurs.

LPCD_Irq

Set if a card is detected in Low-power card detection sequence.

Timer4Irq

Set to logic 1 when Timer4 has an underflow.

Timer3Irq

Set to logic 1 when Timer3 has an underflow.

Timer2Irq

Set to logic 1 when Timer2 has an underflow.

Timer1Irq

Set to logic 1 when Timer1 has an underflow.

Timer0Irq

Set to logic 1 when Timer0 has an underflow.

Irq_Inv

Set to one the signal of the IRQ pin is inverted

Hi AlerIrqEn

Set to logic 1, it allows the High Alert interrupt Request (indicated by the

bit HiAlertIrq) to be propagated to the GlobalIrq

Lo AlertIrqEn

Set to logic 1, it allows the Low Altert Interrupt Request (indicated by the

bit LoAlertIrq) to be propagated to the GlobalIrq

IdleIrqEn

Set to logic 1, it allows the Idle interrupt request (indicated by the bit

IdleIrq) to be propagated to the GlobalIrq

TxIRqEn

Set to logic 1, it allows the transmitter interrupt request (indicated by the

bit TxtIrq) to be propagated to the GlobalIrq

RxIRqEn

Set to logic 1, it allows the receiver interrupt request (indicated by the bit

RxIrq) to be propagated to the GlobalIrq

ErrIRqEn

Set to logic 1, it allows the Error interrupt request (indicated by the bit

ErrorIrq) to be propagated to the GlobalIrq

RxSOFIrqEn

Set to logic 1, it allows the RxSOF interrupt request (indicated by the bit

RxSOFIrq) to be propagated to the GlobalIrq
