2.3.1 Input Parameter

There is only one input parameter, an unsigned integer "count". This parameter determines the maximum number of PLL lock attempts to try before exiting with an error. If a count of zero is given, the routine continues to attempt a proper PLL lock until successful. The value chosen for count determines the maximum execution time of the workaround function.
