LCD NORMAL/BY-PASS MODE SELECTION
The external modem or MCU can access the system interface LCD Panel through the by-pass. After reset, the
initial output path of LCD controller is by-pass like described in below figure 14-10. In order to operate in the
normal display mode (RGB or CPU I/F), SEL_BYPASS[3] value @ 0x7410800C must be set as ‘0’(normal mode)
instead of ‘1’(by-pass mode).
