Hi,
I have to implement sleep mode in LPC3250, i have done a study in the datasheet and found that the mode supporting sleep is STOP mode in LPC3250.
The challenge i am facing is, since my code is running on external ram and to go in STOP mode i have to go via Direct Run Mode and in Direct Run Mode i cannot access the external RAM, that's why my system is restarting.
one possible solution i thought is to put the specific code related to sleep on internal RAM (IRAM) of LPC3250.
Please suggest the possible solutions.
can i make transitions like EXTERNAL RAM -> INTERNAL RAM (IRAM) -> EXTERNAL RAM (AFTER WAKE UP).
Thanks in advance...
