7.7 Individual brightness control with group dimming/blinking
A 1.5625 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 (4 bits, 16 steps)
is used to provide a global brightness control.
A programmable frequency signal from 24 Hz to
programmable duty cycle (6 bits, 64 steps) is used to provide a global blinking control
for (24 Hz to 6 Hz) and (8 bits, 256 steps) for (6 Hz to
