using flash NVM to simulate EEPROM

[weightwatcherphil]

I have an application that performs a task and saves the result to EEPROM that uses an ATMEL ATMEGA168pa processor.

I want to convert it to the nRF52840 which does not have any EEPROM.  Is there an app note that shows how to simulate EEPROM using flash memory ?

How many write cycles are allowed on the nRF52840 flash.

thanks

I have been reading more about the nRF52840 and how to write to flash.  I have decided to no longer use flash for constantly buffering data while sending data over the radio.  There appears to be issues with this working correctly.  I think I will just add a serial EEPROM.
