Yes you have to pay attention to the number of writes to flash. I did
embedded/bare metal work before I retired and there were 2 times I wore
out the program flash in uCs. These were NXP chips and they were
probably programmed 10-20 times over 9-12 months.

> The replies about EEPROM versus Flash are correct. An EEPROM will last through 10 times as many writes as a Flash device. Some of the high capacity devices are actually 1/100 of an EEPROM's duration, but I doubt anyone is putting 16GB of NV memory in a module. The only downside is thet EEPROM memory sizes are much smaller, but that won't affect storage of a 2-bit or 3-bit setting. Many PIC and other micro controllers have both Flash and EEPROM for code and settings, respectively.
