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

2. IINJ(PIN) mustnever be exceeded. This is implicitly insured if VIN maximum isrespected. If VIN maximumcannot be respected,

the injection current must be limited externally to the IINJ(PIN) value.A positive injection is induced by VIN > VDD whilea

negative injection is induced by VIN<VSS.

3. VSS and VSSA signals must be interconnected together with a short wire loop

2. All power VDDX (VDD, VDDA) and ground VSSX (VSS, VSSA) pins must always be connected to the external power supply.

3. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum cannot be

respected, the injection current must be limited externally to the IINJ(PIN) value. A positive injection is induced by VIN > VDD

while a negative injection is induced by VIN < VSS

4. Negative injection disturbs the analog performance of the device.

5. When several inputs are submitted to a current injection, the maximum IINJ(PIN) is the absolute sum of the positive and

negative injected currents (instantaneous values). These results are based on characterization with the IINJ(PIN) maximum

current injection on four I/O port pins of the device.
