14 years agoIt is interfaces on LCD controller which is called SSD1325.
--------------------------------------- MPU Interface selection SSD1325 MCU interface consist of 8 data pins and 5 control pins. The pin assignment at different interface mode is summarized in Table 6. Different MCU mode can be set by hardware selection on BS[2:0] pins (please refer to Table 5 for BS[2:0] setting).
