2.4 Execution Time

The execution time is a function of the crystal frequency and the number of iterations required for the PLL to lock. The maximum execution time is then a function of the maximum iterations allowed, which is the only parameter passed to the function. The _errata_SSWF021_45_both_plls() function minimizes execution time by locking both PLLs simultaneously. Example execution times for the single PLL _errata_SSWF021_45_pll1() and _errata_SSWF021_45_pll2() functions are shown in Table 1. Example execution times for the dual PLL _errata_SSWF021_45_both_plls() function is shown in Table 2.
