I tried some test code the other night, and I did not get what I was expecting.
I thought I could each of the text pages on the 9938 to have their own unique character sets for characters 0 to 255. So, simply by flipping from one page to another, besides changing what was on the screen, it would also use the new character set if one was different.
I'm using a mixture of of the VIDEO XOP's and direct video writes.
Is there any reason why my thoughts are not correct?
