The Smart EVB G2 provides two touch panel interfaces: J0804 and J0802.
J0804 is used for the connection between touch panel interfaces of main LCM and EVB.
J0802 is used for the connection between touch panel interfaces of secondary LCM and EVB.
The following figure shows a reference design for touch panel interfaces.
