1. AUTO bit set
2. PLL stabilization delay is highly dependent on operational requirement and external component values (i.e. crystal, XFC
filter component values|). Note (3) shows typical delay values for a typical configuration. Appropriate XFC filter values
should be chosen based on operational requirement of system.
