Library of self-test software functions and guidelines to assist compliance with the IEC60730 class B safety standard for household appliances.


Electronic household appliances require specific testing to ensure safety and reliability compliance. Class B standards are control functions intended to prevent unsafe operation.


The diagnostics software library contains software tests for the CPU, volatile memory (user RAM), non-volatile memory (Flash ROM for code and data storage), Clock Frequency Accuracy Measurement Circuit (CAC), Independent Watchdog (IWDT), Low Voltage Detection (LVD) module, 14-bit A/D Converter (ADC14), and Port Output Enable for the GPT (POEG) module.


The software routines can be implemented in any system for self-testing of Synergy S124 MCUs. The routines are to be used after reset and during program execution, but can be integrated into the overall system design as desired.
