INFO knob
The INFO knob has a rotate and press function. It is used to activate menus and switch between them. The INFO knob can be turned to 18 distinctive
positions. The press function is used for confirmation when making settings. SIDC sends a 5V 960Hz PWM signal with a pulse ratio of 90% from pin 4
to ICM pin 14 when activating the press function.
The rotate function is supplied with 5V on pin 1 from ICM pin 11 and with 5V on pin 2 from ICM pin 12. SIDC grounds the respective pins in a certain
order when turning the knob in one direction and in the opposite order when turning it in the other direction. ICM registers how far the knob is turned
and in which direction.
