Electrical characteristics
Prequalification trials
Most of the common failures (unexpected reset and program counter corruption) can be
recovered by applying a low state on the NRST pin or the oscillator pins for 1 second.
To complete these trials, ESD stress can be applied directly on the device, over the range of
specification values. When unexpected behavior is detected, the software can be hardened
to prevent unrecoverable errors occurring. See application note AN1015 (Software techniques
for improving microcontroller EMC performance).

Electromagnetic interference (EMI)
Based on a simple application running on the product (toggling 2 LEDs through the I/O ports),
the product is monitored in terms of emission. This emission test is in line with the norm SAE
IEC 61967-2 which specifies the board and the loading of each pin.
