CPLD CoolRunner-II - Can the specialty pins be used as general I/O?


CoolRunner-II has dual purpose pins, such as GTS, GCK, GSR, CDRST and DGE. Can they be used as a general user I/O?


The dual purpose pins GTS, GCK, GSR, CDRST and DGE can all be used as general user I/O.

If the clock divider is used in the design, then CDRST cannot be used as a general purpose I/O, even if the reset port of the clock divider is not used. See (Xilinx Answer 24517).
