Figure 3. MPC8349E Interrupt Circuitry
Following are descriptions of the interrupt signals shown in Figure 3 :
? Local bus connector interrupt (LEXP_IRQ1, LEXP_IRQ0). The local bus expansion connector has
two interrupt signals that are ORed on the MPC8349E-mITXE board and generate an interrupt to
the MPC8349E IRQ1.
? PHY interrupt (GBE1_IRQ) and RTC interrupt (RTC_IRQ).The VSC8201 GBE PHY interrupt is
ORed with the DS1339 RTC interrupt and connected to IRQ2 of the MPC8349E. Therefore, the
system software can detect the status of the Ethernet link, the PHY internal status, and the RTC
status.
? PCI interrupt (PCI_INTA, PCI_INTB). The 32-bit PCI slot INTA and INTB are connected to the
IRQ4 and IRQ5 of the MPC8349E, respectively, and the MiniPCI INTA is connected to IRQ5 of
the MPC8349E.
? SATA interrupt (SATA_INTA). The on-board SATA controller (SiI3114) interrupt signal is
connected to the IRQ6 of the MPC8349E.
? USB over current (USB1_IRQ, USB2_IRQ). The USB1 and USB2 power supplies have an over
current detection circuit and generate an interrupt when the current limit reaches (2A) or a thermal
shutdown or under voltage lockout (UVLO) condition occurs. These two interrupt pins are ORed
to generate an interrupt to IRQ3 of the MPC8349E.
? Compact Flash interrupt (PCCARD_IRQ) and L2 Switch (VSC7385) interrupt (L2_IRQ1,
L2_IRQ0). The L2 Switch (VSC7385) has two IRQs that are ORed with the compact Flash
interrupt signal and generate an interrupt to the MPC8349E via the IRQ7 signal.
