JP4 - GPIO0 Polarity on H1
JP4 selects the polarity of the GPIO0 signal available on the LCD Connector H1.
Position 1-2 sends the GPIO0 signal directly to H1 (default setting).
Position 2-3 inverts the GPIO0 signal before sending it to H1.
When no jumper is installed, GPIO0 is not sent to H1.

JP5 - GPIO0 Selection
JP5 selects the function of the GPIO0 signal.
Position 1-2 GPIO0 used to control the LCD bias power supplies for STN panels.
Position 2-3 GPIO0 used as the PS signal when the S1D13A04 is configured for HR-TFT
panel type.
