2. VREF+ must be always lower or equal than VDDA (VREF+ ≤VDDA). If unused then it must be connected to VDDA.

3. VIN maximum must always be respected. Refer to Table 22: Current characteristics for the maximum allowed injected

current values.

4. Include VREF- pin.

1. All main power (VDD, VDDA) and ground (VSS and VSSA) pins must always be connected to the external power supply, in the

permitted range.

2. This current consumption must be correctly distributed over all I/Os and control pins.The total output current must not be

sunk/sourced between two consecutive power supply pins referring to high pin count LQFP packages.

3. Positive injection is not possible on these I/Os and does not occur for input voltages lower than the specified maximum

value.

4. A positive injection is induced by VIN > VDD while a negative injection is induced by VIN< VSS. IINJ(PIN) must never be

exceeded. Refer to Table 21: Voltage characteristics for the maximum allowed input voltage values.

5. A positive injection is induced by VIN > VDDA while a negative injection is induced by VIN< VSS. IINJ(PIN) must never be

exceeded. Refer also to Table 21: Voltage characteristics for the maximum allowed input voltage values. Negative injection

disturbs the analog performance of the device. See note (2) below Table 70.

6. When several inputs are submitted to a current injection, the maximum

ΣIINJ(PIN) is the absolute sum of the positive and

negative injected currents (instantaneous values).
