The rep (for Atmel-WM) says that I can set this with software and jump from internal code to external code. Has anyone had any luck with this??
Will clearing LB1 allow the processor to be effected by !EA
I never tried this personally. All I know is that the manual does say "If security level 1 is programmed /EA will be internally latched on reset.".
How do you change this register? The white paper doesn't say...no address anyway. Do I need to use a programmer of some kind?
Here is my (non expert) take on reading the Rev F data sheet. Since the default value is level 4, you need to use a parallel programer to erase the chip the reload the boot loader (available from ATMEL). This should put you at level 0. Yuck.
I just got that same explanation from the Temic rep. Thanks, I do appreciate all the help. Stephen Kerslake
