I am trying to set a watchpoint for a global variable. when I click on "Toggle Watchpoint" after selecting a variable, there is a "range" option along with the other options(like read, write).
Is the "range" option used to program the mask register of comparator in DWT hardware to trigger a debug event, if an access is made in the range of addresses?
Is it effective in LPCXpresso v8.2.2?
I tried setting the range with different values and access memory locations with in the range, I cannot trigger a debug event for this.
Debug event is triggered only for the first address.
If the "range" option is effective, please tell me how I can use the it?
