It takes 500 s max. for the oscillator to be up and running once SLEEP bit has been set to logic 0. Timings on LEDn outputs are not
guaranteed if PWMx, GRPPWM or GRPFREQ registers are accessed within the 500 s window.
When the oscillator is off (Sleep mode) the LED outputs cannot be turned on, off or dimmed/blinked.
