Interface to other NAT-MCH PCBs
Basic PCB
: - The Microprocessor on the
CLK Module
can be programmed
by the ColdFire on the
Basic-Module
via a SPI interface.
Normal communication between the Microprocessor and the
ColdFire is done by IPMI messages via the I²C interface.
- The external clock interface on the front panel is connected to
the
CLK Module
via the interface to the
Basic-PCB
(via
connector CON2).
PCIe Hub-PCB
: - The
CLK Module
can receive a PCI Express compliant clock
signal from the
Hub-PCB
(only PCI Express versions).
