Hi All,
I have a basic question about ATOM packet observed using OpenCSD.
Taking below example: I_ATOM_F3 : Atom format 3.; NEE So "N" is for first conditional branch or last conditional branch on code?
Thanks -Bharat
HI,
The OpenCSD decoder uses the same format as Atom format 1-3 packets - i.e. the least significant bit is the oldest emitted atom. So this display the atoms occurred in the order E, E, N, the first E being the oldest, the N being the newest.
Regards
Mike

HI,
A quick revision to my last - the decoder _stores_ the atoms LSBit oldest - so if programmatically analysing the packet this is the ordering you require, but checking the display code it _displays_ in order from oldest to newest, so the display NEE has an oldest to newest ordering matching the ETMv4 documentation which represents atom sequences in that order.
