External Interrupts

Figure 5

shows the external interrupts to the MPC8313E.

Figure 5. MPC8313E Interrupts

The following are descriptions of the interrupt signals shown in

Figure 5

•

All external interrupt signals are pulled up by 4.7 K

resistors.

•

IRQ0 is connected to SD Card

•

IRQ1 is connected to PCI slot INTA.

•

IRQ2 is connected to and shared by the PCI slot’s INTB and the mini PCI slot INTA.

•

IRQ3 is connected to the L2 switch as well as to an external USB PHY (by an optional resistor).

•

IRQ4 is connected to the Marvell GBE PHY as well as to RTC and LM75 (by an optional resistors).
