If you wish to build a system that can accept either managed or unmanaged Galaxy devices in the same socket,
be sure to pull the CPU interface pins high through a resistor or jumper. That way you can make it a “stuffing
option” to disable the CPU interface or to implement it when a GT-48208/212 is installed.
19.4
CClk in an Unmanaged System
The CPU clock (CClk) must have a clock source applied in any Galaxy system even when no CPU is present (this
is also true for the GT-48207). This ensures a proper RESET condition throughout the device. In an unmanaged
system, connect CClk to either the 25MHz 10/100 PHY clock or to the 20MHz 10Mbps PHY clock.
NOTE: Do not tie AClk to CClk, this will result in synchronization failures. Tying AClk to CClk was recommended in
previous documentation, however, this is incorrect information.
