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 the following table.
