1. Specified by design - Not tested in production.
2. The fall time is defined between 70% and 30% of the output waveform, according to I 2 C specification.
3. This value represents the I/O capability but the maximum system frequency is limited to 48 MHz.

1. Refer to Table 51: I/O AC characteristics .

Stresses above the absolute maximum ratings listed in Table 20 , Table 21 and Table 22 may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these conditions is not implied. Exposure to maximum rating conditions for extended periods may affect device reliability.

All voltages are defined with respect to V SS .

1. A positive injection is induced by V IN > V DDIOx while a negative injection is induced by V IN < V SS . I INJ(PIN) must never be exceeded. Refer also to Table 20: Voltage characteristics for the maximum allowed input voltage values.
2. When several inputs are submitted to a current injection, the maximum ∑ |I INJ(PIN) | is the absolute sum of the negative injected currents (instantaneous values).
