I have just read in the Anomaly Sheet for ADUC845/7/8 (link: http://www.analog.com/static/imported-files/data_sheets/ADUC845_847_848ANOMALY.pdf) something that I don't understand.
This is 6 case in this document about Stack pointer in ULOAD mode.
It is requirement to always set SP to 0x07 when entering ULOAD mode in 'user-code' Bootloader code? What if not? What value set to SP when exiting from ULOAD mode to NORMAL mode?
