(Note 4)
The MHZ66_CLK is first inverted and then fed to all these domains.
Each domain receives the referenced clock and performs the divide just before the CCU.
This clock differs from other clocks in this table in that this clock does not utilize a CCU nor is it subject to GLCP control or power
management control.
This logic does not have a fixed clock source. During debug it is switched to the clock domain of interest. It does have a CCU.
