The system triggers A/D conversions every 30 minutes via timers, stores results using the Data Transfer Controller, and evaluates data levels with the Data Operation Circuit. If data exceeds thresholds, the MCU exits low-power mode to transmit data via UART. The system also supports user-initiated data transmission and periodic data output every 24 hours. Key peripherals include ADC, DTC, AGT timers, RTC, ELC, DOC, and low-power modes, all managed via Renesas e2 studio IDE and Flexible Software Package.相关文件：
