I am currently working on the ADUC7023 microcontroller and I am using the NI USB-8452 for programming.
I am wondering what could be the consequence of programming the flash memory without erasing all the flash memory before ? Could it be critical the first time the microcontroller is programmed ? Could it be critical to program the flash memory several times without erasing it before ?
Are there probabilities to have bad retention data in the product lifetime because of a bad programming sequence ?
Could data retention be affected by temperature (80-100°C) if programming sequence has not been respected ?
I hope you could answer to my questions.
Thanks in advance for your support !
