ITOT_INJTotal current injection per power rail or per ground rail(5)±2 mA
Note:
  1. In this table, VDD refers to the voltage of the associated power rail of the I/O line, as defined in Pinout. For example, for PA2, VDD refers to VDDSDMMC.
  2. Input voltages VIN ≤ 0V or VIN ≥ VDD lead to negative or positive current injection on inputs.
  3. For analog inputs (PD19..PD31), input voltages VIN ≥ min(VDDANA, VADVREFP) lead to saturated A/D conversion to 0xFFF.
  4. Current injection on inputs (PD3..PD31) may degrade the analog performance of the corresponding channel (A/D converter or PTC) or the analog performance of other analog channels.
  5. Corresponds to the sum of the positive currents into one power rail and respectively to the sum of the negative currents into one ground rail as defined in Pinout.
