单端输入的正确配置方法在EVM user's guide P17 有描述：www.ti.com.cn/.../slau443b.pdf
1. Set all jumpers to factory defaults as described in Section 2.5.
2. Remove jumpers from pin 5-36 of J6.
3. Short pin 5 and 6 of JP25. Set the SRB1 bit in the MISC1 register to route the SRB1 pin to the

to the negative inputs of the channels through the SRB1 pin.
4. Provide the single-ended inputs to pins 36, 32, 28, 24, 20, 16, 12, 8 of J6 for channels 1-8 respectively
