EEPROM update on commands not requiring AT&W


our application sends periodically init commands to the GSM module.

One of those is AT+WRIM=0 (always with the parameter zero)

Documentation says that ‘parameters are stored in EEPROM without using the AT&W command’

But does an update also take place if there was no change in the parameter?

And if there is an update: how many programming cycles does the EEPROM have?
