Hello. How can a application that uses Xdata Pages co-exist with variables placed in a separate Xdata page according the C51 Large Model? Our ADI uC812 based application manipulates the xdata page pointer DPP to save sampled data. We setup the large model (we thought) to use a separate page area via DPP. We attempted to save and restore the C51 DPP page value and then migrated from small model to large model. Of course the code broke. Any help appreciated. Thanks. Wil Blake
