All external interrupt signals are pulled up by 4.7 K resistors.
MCU interrupt (MCU_IRQ), RTC interrupt (RTC_IRQ) and Thermal interrupt (THERM_IRQ).
The MCU and DS1339 RTC interrupts are ANDed the thermal interrupt. However, MCU interrupt
is the main function for this IRQ pin. RTC and thermal interrupt are optional so they are
disconnected from the AND gate by default.
PHY interrupt (TSEC1_IRQ). The RTL8211B GBE PHY interrupt is connected to IRQ1 of the
MPC8308. Therefore, the system software can detect the status of the Ethernet link and the PHY
internal status.
USB over current (USB_IRQ). The USB power supply 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. It is connected to IRQ3 of the MPC8308.
L2 Switch (VSC7385) interrupt (L2_IRQ1, L2_IRQ0). The L2 Switch (VSC7385) has two IRQs
that are ANDed together to generate an interrupt to the MPC8308E via the IRQ4 signal.
