MC9S12G128 wake up from Pseudo Stop Mode,After Wake up Where is the program running position? if MCU wakes up from Isr,How to make the chip rerun to the main function without resetting？
the code continues with the interrupt which has woken the MCU up and the it goes to the next code after the instruction asm STOP where you put the MCU to stop/pseudo stop mode.
2) If you want to return to main then just use main();
Of course, if you want to go to start of the code which uses also Startup function (CodeWarrior) you should:
a) define the function in the module you will call the Startup() from.
For example modue main.c will contain:
b) Call the function at the place you require.
Do not forget that some register are write once only so they will not be changed by new write.
Please look into attached example it solves something similar....
I have resoved the question alreadly,thank you very much!
One more thing, however, came to my mind.
Thank you for response, one thing I would like only to highlight. If you go directly to the start of the code but behind the place where stack is initialized you have to process/reinitialize the stack (LDS).
If you want to find the original stack value then search for code LDS in the file start12.c.
Thank you for your Calling attention to that,However,Software restart function——_Startup() is before initializing the stack ,RAM and so on,so,I dont have to worry about the question.
if I get error somewhere else,Please point it out,thank you.
