so 1. All power (VDD) and ground (VSS) lines must always be connected to the external supply.

b 2. IINJ(PIN) must never be exceeded. This is implicitly insured if VIN maximum is respected. If VIN maximum

O 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. For true open-drain

- pads, there is no positive injection current, and the corresponding VIN maximum must always be respected.

) 3. Negative injection degrades the analog performance of the device. See note in Section 12.13.3: ADC

t(s accuracy on page 174. If the current injection limits given in Table 104: General characteristics on

page 162 are exceeded, general device malfunction may result.

uc 4. 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). These results are based on

d characterization with ΣIINJ(PIN) maximum current injection on four I/O port pins of the device.

ro 5. True open drain I/O port pins do not accept positive injection.
