Hi,

when saving values in a flash memory block with IAP functions all interrupts have to be turned off. For reliable use of this flash memory with the rest of the program I am interested in the speed of this flashing procedure.

Do you know how long it takes to save e.g. 512 bytes? Of course I could measure it but maybe someone has already done this or has experience with it.

Thanks!
Martin

More or less 100ms (= 0.1s, no typo). That's the time to erase the sector.
