I'm working on getting my project manufactured, and I'm wondering if it is possible to get the chip pre-programmed by Atmel or external chip vendor (to protect my code)?
Can the program be read-protected, but the EEPROM be read/write accessible? There are some controller gains that I'd like to have the manufacturer adjust by programming the EEPROM only.
The manufacturer is doing everything else, and while in the US, has a china factory. I'm a bit worried about them having the entire design... any thoughts/advice would be great.
