eFuse Layout
Click 
on the left side of the main interface of GProgrammer to open the eFuse Layout interface.
GProgrammer presents users with eFuse layout information: Offset, Value, Length, and Comments of fields including but not limited to Product ID, Chip ID, EncMode, SWDDisable, Config, and IO_LDO_SEL. Among them, the Config and IO_LDO_SEL fields contain multiple bit fields.
Click Refresh to obtain the values of all fields or bit fields.
Click 
before Offset of Config or IO_LDO_SEL to expand the detailed bits, as shown in the figure below. Click 
or double-click Config or IO_LDO_SEL to collapse the detailed bits.
You can change the IO_PWR_SRC value in the IO_LDO_SEL field to set the power source of peripherals.
You can only change the IO_PWR_SRC value from "0" to "1". The contrary direction is not allowed.
The fields and bit fields listed in the interface are stored in the efuse_config.json file in the config folder. Information stored in eFuse is more than just the listed fields and bit fields.
