TPL1401EVM: How to use EEPROM or NVM？

How does TPL1401 use EEPROM or NVM?

1，I set DPOT_PDN, REF_EN, DAC_SPAN and DPOT_POSITION, but they need to be reset every time the power is restarted. I tried many parameters but could not save the parameters.

2，Also, why is page 1 set to power-up but the DPOT_PDN of page 2 set to 10K power-down?

您好，

配置好DPOT_PDN, REF_EN, DAC_SPAN and DPOT_POSITION，您是否点了EEPROM PROGRAM 按钮了？点了之后就将最新的寄存器值写入EEPROM了，掉电重启后，再点击 RELOAD按钮就将EEPROM的配置加载到设备了。

第2问题是什么意思？您想实现什么操作？

I did it by the way what you said, but RELOAD did not implement the data stored by PROGRAM after power-on.

The Settings and registers in the OUTPUT POWER UP/DOWN of the Basic DPOT page are inconsistent
