ADS1220 Offset calibration 读取操作咨询

Other Parts Discussed in Thread: ADS1220, ADS1120

将ADS1220 设置成如下所示状态读取偏移校准用的数据。但是实际读出的数据却是混乱无章的数据，我不太清楚是哪里弄错了。读出的数据有0x-10000 、0x16，0x1，0等等。
 
Temp=0xE1;
  ADS1220WriteRegister(ADS1220_0_REGISTER, 0x01, &Temp);
 Temp=0x00;
// Temp=0x00;
 ADS1220WriteRegister(ADS1220_1_REGISTER, 0x01, &Temp);
// Temp=0x80;
 Temp=0x10;
 ADS1220WriteRegister(ADS1220_2_REGISTER, 0x01, &Temp);
 Temp=0x00;
 ADS1220WriteRegister(ADS1220_3_REGISTER, 0x01, &Temp); 
设置成如下所示 读取采样pin脚的数据是正确的。
 Temp=0x01;
  ADS1220WriteRegister(ADS1220_0_REGISTER, 0x01, &Temp);
 Temp=0x00;
 ADS1220WriteRegister(ADS1220_1_REGISTER, 0x01, &Temp);
 Temp=0x10;
 ADS1220WriteRegister(ADS1220_2_REGISTER, 0x01, &Temp);
 Temp=0x00;
 ADS1220WriteRegister(ADS1220_3_REGISTER, 0x01, &Temp);
