describes the EIDR fields.
External signal. Allows interrupt to be serviced externally. EP should be set only for level-sensitive external
interrupts (EIVPR n [S]= 1). Setting for edge-sensitive does not provide reliable interrupt response.
0 Interrupt is not routed to IRQ_OUT.
1 Interrupt is routed to IRQ_OUT for external service.
Critical interrupt 0. Ci n fields should be set only for level-sensitive external interrupts (EIVPR n [S]= 1). Setting them
for edge-sensitive does not provide reliable interrupt response.
0 Processor core 0 does not receive this interrupt.
1 Directs the external interrupt to processor core 0 by causing the cint0 output signal from the PIC to assert. See
External Interrupt Destination Registers (EIDR0–EIDR11)

Reserved, should be cleared.
Polarity. Specifies the polarity for the external interrupt.
0 Polarity is active-low or negative edge-triggered.
1 Polarity is active-high or positive edge-triggered.
Sense. Specifies the sense for external interrupts.
0 The external interrupt is edge sensitive.
1 The external interrupt is level sensitive. This setting must be used to direct the interrupt to IRQ_OUT or cint .
Note: If an IRQ n signal is used to receive INT x signals from one of the PCI Express ports as a root complex,
S must be set to be level-sensitive.
Reserved, should be cleared.
0 inhibits signalling of this interrupt to the core. Affects only interrupts routed to int .
