PPAGE Use Problem.

I am using a 9s12G128, CodeWarrior for the Code.  Banked Memory Model.  I have code in loaded into Page 8 (PPAGE 8), and data in Page 9 (PPAGE 9) . 

 

Can (banked) code running from Page 8 access data in Page 9?    When I run in the debugger, it seems that the data access to the Page 9 data changes the PPAGE register, but does change the PPAGE value back to Page 8 once the data read is complete.

 

Or, if you access data in Paged Flash, must the code be executing from non-paged memory?
