Product features:
CH32V103 series is a 32-bit general-purpose microcontroller with RISC-V3A processor as its core,
The processor is designed based on RISC-V open source instruction set. It integrates clock security mechanism, multi-level power management and general DMA controller.
This series has rich peripheral resources such as one USB2.0 host/device interface, multi-channel 12-bit ADC conversion module, multi-channel TouchKey, multiple sets of timers, multi-channel IIC USART SPI interface, etc.
The microcontroller is equipped with a complete software and hardware platform and debugging interface tools, which can meet various needs in the industrial, medical, consumer and other markets, and is widely used in: motor drive and application control
Application fields: widely used in motor drive and application control, PC game peripherals and GPS platforms, programmable controllers, frequency converters, printers, scanners, alarm systems, video intercoms, heating, ventilation and air conditioning systems and other occasions.

1. Query chip read protection status;
2. To set the chip read protection, the power-on configuration takes effect again;
3. To remove the chip read protection, the power-on configuration takes effect again;
