    I am using the 79520 SDK without an operating system and have a need for a timer tick. I notice that LOLO seems to use Time0 for a 1MS timer tick interrupt, which is exactly what I need. So rather than setting up my own timer-tick interrupt, I thought I would just read the tick value already kept by LOLO.

    Can someone tell me where the timer tick value that LOLO keeps is stored, and what size it is?

    David,

    Sorry for the delayed response on this:

    Due to ongoing development with LoLo this probably isn't t the best idea since these are not static values. I have not tested this myself but these are the addresses that should work with the latest version of LoLo on the 9520.

    You should be able to find them at the following :
    2003612c : ticks_ms
    20036130 : ticks_s

    You can use the 'x' command in LoLo to examine these registers. In theory this should work but it may not. You may end up having to implement your own timer.

    Thanks,
