synthesizer is already operating at some stable frequency.
in some configuration bits may take longer to stabilize inside the chip (such as internal clock
synthesizer-related bits 4 and 5). The recommended configuration bit setup time is T
that the chip is in a completely stable state when Reset goes inactive.
