EEPROM simultaneous operations

AjRj14 — Fri, 01 Jul 2022 10:39:22 GMT

Hi ,

I am erasing and writing 40 bytes in EEPROM.

To erase and write 40 bytes in EEPROM, approximately 53 ms of time is required.

But our application has many different ISRs scheduled.

Is it allowed to execute ISRs during EEPROM erase/write operations.?

Thanks in advance.

Interrupts of course are allowed during EEPROM erase/program times. Just keep in mind that EEPROM is not readable while any EEPROM command is in progress.

But our application has many different ISRs scheduled.

What has this to do with EEPROM operation? Simultaneously you can't execute more than one EEPROM command

¿Te refieres a D-Flash (EEPROM), qué micro usas?
