    Smile Do READ and WRITE for PIC16F690 onboard EEPROM need 10ms pause?

    Hi,

    Do I need to add a 10ms pause after a READ or WRITE to the onboard EEPROM in a PIC16F690?
    I could not fine any info about that in the PBP manual or in the datasheet of this PIC.

    Thanks!

    How many times are you going to post the same basic question?

    One is about the internal eeprom, the other one is about an external EEPROM chip.

    READ or I2CREAD does not need a pause - ever. Whether it is external or internal EEPROM it does not matter.

    WRITE (for internal EEPROM) does not need a pause as it is handled already by PBP.

    I2CWRITE however DOES need a pause because PBP does not know if you are writing to an EEPROM or some other I2C device. Check with your external I2C devices Datasheet to see what your pause (if any) should be.
