You can select the clock source and the clock speed in the Programming Object File
Options window with pof selected as the programming file type (Convert
Programming Files window), as shown in
external clock frequency in the Frequency (MHz) drop-down menu, and select any
value from the divisor list regardless of the clock source setting.

The enhanced configuration device is a single-chip configuration solution that
provides increased configuration flexibility and faster time-to-market. Features such
as data compression, multiple clock sources, clock division, and parallel or concurrent
programming significantly reduce configuration times, while the dynamic
configuration mode and the external flash interface take intelligent system
configuration to a higher level.
