The MAX17201, MAX17205, MAX17211, and MAX17215 are limited to 7 writes to NV memory.
As such, it is useful during design to be able to test numerous configuration settings to optimize performance.
In order to test configurations without using an NV write, please follow the following procedure:
- Go through configuration wizard (in the EVKit software, no EVKit is needed) step by step.
- In the last step, save the INI file to local directory. The INI file should have all parameters from 0x180 to 0x1DF.
- In the application, the host MCU will write all values in INI file from 0x180 to 0x1DF to shadow memory.
- It is then followed by fuel-gauge reset of write 0x01 to 0xBB to take effect.
- Wait for FSTAT.DNR bit to clear
