These clock select signals can be dynamically controlled through internal logic when the device is operating in user
mode.
These clock select signals can only be set through a configuration file (SRAM Object File [.sof] or Programmer Object
File [.pof]) and cannot be dynamically controlled during user mode operation.
These clock select signals can only be set through a configuration file (.sof or .pof) and cannot be dynamically
controlled during user mode operation.
Only the CLKn pins on the top and bottom of the device feed to regional clock select.
