Programming Header Header for programming Cyclone

EP1C12Q240.

Factory Use

Header used for debugging purpose.

A/D Input settings (
see page 3 for
settings)

The software programmable PGA allows
selecting an input range of +/-10v, +/-5v, +/-
2.5v, or +/-1.25v, based on a gain of 1, 2, 4,
or 8, when the A/D is selected with a +/-10V
range by jumper.
