TE0320 is provided with a slide switch S2.
Figure 33: Slide switch S2 (angle view).
Slide switch S2 conditions the value of signal PS_EN. Signal PS_EN enables (high) or disables (low) power rails 2.5V and 1.2V. According to the corresponding assembly option, power rail VCCCIO0 can depend or not on the 2.5V power rail. Power-rail 3.3V is not controlled by signal PS_EN and is unconditionally enabled. Table 14 summarizes all switching options implied by slide switch S2 under the standard assembly option.
