3.2 Configuration Jumpers
The S5U13706B00C has seven jumper blocks which configure various setting on the
board. The jumper positions for each function are shown below.
JP1 - GPIO0 Connection
JP1 selects whether GPIO0 is connected to SW1-9. SW1-9 is used to enable hardware video
invert on the S1D13706.
When the jumper is on (position 1-2), SW1-9 controls the hardware video invert feature
(default setting).
When the jumper is off, the hardware video invert feature is disabled. This setting must be
used for HR/TFT and D-TFD panels as GPIO0 is required in each panels LCD interface pin
mapping. Refer to the S1D13706 Hardware Functional Specification, document number
X28B-A-001-xx for details.
Note
When configured for Sharp HR-TFT or Epson D-TFD panels, JP1 must be set to no
jumper and JP6 must be set to position 2-3.
