PIC16F1459在断电期间存储数据

嗨，新手问题。我的应用程序需要微控制器在设备关机时存储用户保存的数据，然后在被备份时读取存储的用户保存的数据，因此应用程序不需要每次重新校准。我认为我正在寻找的是一个用于存储非易失性数据的内部EEPROM，但我没有在PIC16F1459数据表中看到任何类似的数据。我看到了使用以下寄存器的Flash程序存储器控制：PMCON1·PMCON2.PMDATL.PMADR.PMADRL.PMADRHTO ME，这似乎更像是用来锁定代码在微控制器编程之后被读取或更改。或者，IS也被用来存储应用程序的“保存”数据？我应该完全看一个不同的特性还是我唯一的选择是一个外部EEPROM？谢谢！

    Hi, newbie question. My application needs the microcontroller to store user saved data when the device will be powered off and then read the stored user saved data when it is powered back on so the application does not need to be re-calibrated each time. What I thought I was looking for was an internal EEPROM used for storing non-volatile data, but I didn't see anything like that in the PIC16F1459 data sheet. I did see Flash Program Memory Control  that uses the following registers:

• PMCON1
• PMCON2
• PMDATL
• PMDATH
• PMADRL
• PMADRH

To me it seems like this is more intended to be used to lock your code from being read or changed after the microcontroller is programmed. Or is is also intended to be used to store "saved" data for the application? Should I be looking at a different feature entirely or is my only option an external EEPROM?

Thanks!
