Only D[4:0] = 0 0000 to 1 1011 are allowed and will be acknowledged. D[4:0] = 1 1100 to 1 1111 are reserved and will not be
acknowledged.
When writing to the Control register, bit 4 must be programmed with logic 0 for proper device operation.
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.
