PWM is the PWM output
 I-button pressed for shorter than 0.5 s: ON
(Restore duty cycle stored before last
switch-off).
 O-button pressed for shorter than 0.5 s:
OFF
 O-/I-button pressed longer than 0.5 s:
Duty cycle variation from 10% up to 100%
(O=less, I=more; ~300 PWM steps, in-
crement every 15 ms). Duty cycle variation
stops when button is released.
PWM_IND is active as long as duty cycle is
not 0%
