Electrical characteristics

Functional susceptibility to I/O current injection

While a simple application is executed on the device, the device is stressed by injecting

current into the I/O pins programmed in floating input mode. While current is injected into

the I/O pin, one at a time, the device is checked for functional failures.

The failure is indicated by an out of range parameter: ADC error, out of spec current

injection on adjacent pins or other functional failure (for example reset, oscillator frequency

deviation, LCD levels, etc.).

The test results are given in Table 41.

Note:

It is recommended to add a Schottky diode (pin to ground) to analog pins which may

potentially inject negative currents.
