D-Bug12 BREAKPOINTS IN PAGED MEMORY - 9S12C32

  Device MC9S12C32 has 2 pages of paged memory at 8000.
  Hardware breakpoints.

D-Bug12
  1. When I enter br 00:8000, I get "Bad extended address".

  2. When I enter br 8000 and run my program at 8000, it never breaks.

  3. If I set 002A to 00 before running, it breaks ok.  However it reports "Target stopped for unknown reason".

  4. I can only enter br 3e:8000 and br 3f:8000 without the error message however neither breaks.


Questions:
  1.  Am I missing something?
  2.  What is the procedure for setting a breakpoint in paged memory?
  3.  What is the range of ppage to be entered with a breakpoint?
  4.  Is there a bug in v4.0.0b32?  Will it be fixed?
