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, 12-bit A/D Converter (ADC12), Temperature Sensor (TSN), and Port Output Enable for the GPT (POEG) module.
The software routines can be implemented in any system for self-testing of Synergy S3A7 microcontrollers (MCUs). The routines are to be used after reset and during program execution, but can be integrated into the overall system design as desired.
