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.
See
mode. Some newer LEDs include integrated Zener diodes to limit voltage transients, reduce EMI, protect the LEDs, and these must be
driven only in the open-drain mode to prevent overheating the IC.
Change of the outputs at the STOP command allows synchronizing outputs of more than one PCA9632. Applicable to registers from
02h (PWM0) to 08h (LEDOUT) only.
