Read interrupt ID on LS1046A via CodeWarrior

AngelMorales — Tue, 16 Nov 2021 17:03:49 GMT

Hi,

As part of some HW preliminary tests, I am trying to monitor if two external interrupt signals (IRQ00 and IRQ02) are being detected by the processor. I see that they are directly routed to GIC-400 within the processor, but I am not sure about which address I should read to get the interrupt ID.

Thank you in advance.

See the Table 5-1 in LS1046a Reference Manual:

Does it mean that they appear on address 0x141_0D18? Or the first 32 bits belongs to the GICD_PPISR register and it is register at 0x141_0D14?
