Thanks for the answer. After recording "tft.begin (0x9320);" to sketch graphictest_kbv, text became displayed correctly. As for the answers to questions (1), (2), (3) after the change of the sketch:
- Modes PORTRAIT, LANDSCAPE, PORTRAIT_REV, LANDSCAPE_REV were printed correctly.
- Vertical scroll mode works properly.
- Software scroll mode works only on EADB red letters in a small window
