.. in the old days of AVR there were some things you needed to do that only parallel programming could handle, like blow a fuse. Which created an impossibility once the chip was soldered down on a target board with only an ISCP header for maybe flash or eeprom updates.
So I would appreciate a sanity check before picking a production method ... that a 6 pin header is enough to do all of the following scenarios, and if not, .. what are the gotchas?
For the atmega328P, can everything be done to a virgin chip over just a 6pin in-circuit serial programming interface (header) soldered on the target board? The 5v board has a 16MHz crystal on it. Using STK500 and Studio 4 for in-house programming.
I'm thinking of my options, of having the assembly house do bulk chip, or post-assembly (soldered down) programming flash and eeprom, over the 6pin header.
Or maybe mixed mode, whereby they do the flash (all the same) but I add just the eeprom config data over the 6pin header.
