Design Tips
Question 1:
Answer 1:
There are a few possibilities, but the most likely is that you did not exactly follow the write
sequence as shown in
are disabled during this sequence.
Question 2:
Answer 2:
The data will only change when a Data EEPROM write occurs. Inadvertent writes may occur
when the device is in a brown-out condition (out of operating specification) and the device is not
being forced to the reset state. During a brown-out, either the internal brown-out circuitry should
be enabled (when available) or external circuitry should be used to reset the PICmicro MCU to
ensure that no data EEPROM writes occur when the device is out of the valid operating range.
Why do the data EEPROM locations not contain the data that I wrote?
Why is the data in the data EEPROM is getting corrupted?
