an extract from Tsuneos quote from SILabs: Any system that contains routines which write or erase FLASH memory involves some risk that the FLASH write/erase routines will execute if the CPU is operating outside its defined operating range of VDD, temperature, or system clock frequency.
to avoid that one (routines which write or erase FLASH), for a product where some data has to be loaded into flash once and once only I have made a program that is "the hoader" and another program without "routines which write or erase FLASH" that is the "application". Thus once the flash data is loaded and the app program has replaced the loader that are no such routines in the chip. Erik |
