Electromagnetic compatibility (EMC) characteristics
Susceptibility tests are performed on a sample basis during product characterization.
4.11.1
Designing hardened software to avoid noise problems
EMC characterization and optimization are performed at component level with a typical application environment and simplified
MCU software. It should be noted that good EMC performance is highly dependent on the user application and the software in
particular.
Therefore it is recommended that the user apply EMC software optimization and prequalification tests in relation with the EMC
level requested for the application.
Software recommendations
The software flowchart must include the management of runaway conditions such as:
