我试图用I2C配置PGA900，我先后配置了
| DIG_IF_CTRL |
| MICRO_NTERFACE_CONTROL |
| TEMP_CTRL |
| ALPWR |
| ADC_CFG_1 |
| TADC_CONFIG |
但是在while中轮询读取
| TADC_DATA1 |
| TADC_DATA2 |
| TADC_DATA3 |
全部是0x00，均没有数据，我用逻辑分析仪查看和i2c读配置的寄存器，都成功配置了，却没有数据
电路是自己做的，仿照pga305 page64
这个是ADC_Config验证寄存器是否配置成功，配置成功。
这个是在while中的读取TADC，返回为0x00
