(5) Setting of BTNSEL is decided when turning the LCD module's power on.
In terms of voltage variation (voltage drop) while VDD rising edge is below 11.4V, a protection
circuit may work, and then this product may not work.
12V for backlight should be started up within 800ms, otherwise, the protection circuit makes the
backlight turn off.
