之前已经实现了两片CC1101的收发功能，后来需要修改freq和MDMCFG寄存器的参数，
CC1101_WriteReg(CC1101_REG_FREQ2, 0x10);
CC1101_WriteReg(CC1101_REG_FREQ1, 0xA7);
CC1101_WriteReg(CC1101_REG_FREQ0, 0x62);
CC1101_WriteReg(CC1101_REG_MDMCFG4, 0xCA);
CC1101_WriteReg(CC1101_REG_MDMCFG3, 0x83);
CC1101_WriteReg(CC1101_REG_MDMCFG2, 0x03);
CC1101_WriteReg(CC1101_REG_MDMCFG1, 0x22);
CC1101_WriteReg(CC1101_REG_MDMCFG0, 0xF8);
另一片cc1101采用查询gdo2引脚接收数据，但gdo2电平不变了
请问是什么问题？
