It takes 500 s max. for the oscillator to be up and running once SLEEP bit has been set to logic 1. Timings on LEDn outputs are not
guaranteed if PWMx, GRPPWM or GRPFREQ registers are accessed within the 500 s window.
No blinking or dimming is possible when the oscillator is off.
Change of the outputs at the STOP command allows synchronizing outputs of more than one PCA9626. Applicable to registers from
02h (PWM0) to 08h (LEDOUT) only.
