PLL_FORCE_OUTPUT_COUNTER
Forces which counter to use for a particular PLL clock output. By default the compiler will automatically
determine the best counter to use based on clock usage and other routing conflicts, but can be overridden
with this option. Using this option can cause clock routing problems, as the clock router cannot rotate
counters to resolve conflicts. Also see option PRESERVE_PLL_COUNTER_ORDER.
