Chip decryption decryption time AT91SAM3S16C

In product research, because the official single chip product are encrypted, using the programmer is not directly read the program. But sometimes due to some reasons, we need to get inside the microcontroller program used to reference research study to find the missing information or copy some chips, which requires single-chip decryption. Cause core can help you.
