Notes to Figure 2–38:  
(1) These clock select signals can only be set through a configuration file (.sof or .pof)  
and cannot be dynamically controlled during user mode operation.  
(2) Only the CLKnpins on the top and bottom of the device feed to regional clock select  
blocks.The clock outputs from corner PLLs cannot be dynamically selected  
through the global clock control block.
