Minimum pulse width for LEDn Brightness Control is 40 ns.
Minimum pulse width for Group Dimming is 20.48 s.
When M = 1 (GRPPWM register value), the resulting LEDn Brightness Control + Group Dimming signal will have 2 pulses of
the LED Brightness Control signal (pulse width = N
This resulting Brightness + Group Dimming signal above shows a resulting Control signal with M = 4 (8 pulses).

A 97 kHz fixed frequency signal with programmable duty cycle (8 bits, 256 steps) is used
to control individually the brightness for each LED.
On top of this signal, one of the following signals can be superimposed (this signal can be
applied to the 4 LED outputs):

A lower 190 Hz fixed frequency signal with programmable duty cycle (8 bits,
256 steps) is used to provide a global brightness control.
A programmable frequency signal from 24 Hz to
programmable duty cycle (8 bits, 256 steps) is used to provide a global blinking
control.
