If GPIO is not used, please refer to the chip datasheet. Some chips have different configurations or software settings when they have higher requirements for low power consumption and EMC. In short, it should be determined according to the manual and reflected in the schematic diagram. As for PCB, it is generated according to the schematic diagram.
