Eeproms; Figure 4-3 Interrupt Circuitry - GE C2K Hardware Reference Manual

Real-Time Clock interrupt, Serial ATA interrupt, Temperature interrupt, and the USB interrupt are
also routed to the MV64460 MPP port (see "Multi-Purpose Pins (MPP)" on page 5-3).
If one of the MV64460 MPP pins assigned as an interrupt is asserted, it sets the corresponding pin
in the Interrupt Cause Register in the MV64460 Interrupt Controller. This causes the Interrupt
Controller to assert the CPU_INT interrupt to the MCP7447A processor.

Address
0x50 Provides storage for product configuration data such as: assem-
bly serial number, build data, etc.
NOTE:
MAC address for the three Gigabit Ethernet MACs must
be stored in this device so the processor can program the MAC
addresses into the MV64460 after power-up or reset.
0x51 Provides storage for customer-specific data.
