We are reading the application report of SSWF021#45 — PLL Fails to Start. workaround.

May i ask two questions:

1. what parameter should i input for the function call _errata_SSWF021_45_pll1() function ?

2. What should i do if the return of below function is not equal to 0 ?

The errata document note www.ti.com/.../spna233a.pdf also describes the input parameter as well as the interpretation of the value returned by the function.

The routine to put the system in a safe state is application dependent, as to what should be the system response if the PLL failed to acquire lock and cannot be used.
