C5 is only needed for 5-wire applications.

D1-D8 are for ESD protection.

- 4-wire touch screen, use D1-D4

- 5-wire touch screen, use D1-D5

- 8-wire touch screen, use D1-D8

See Section 3.8 “ESD Considerations” and Section 3.9 “Noise Considerations” for important information

regarding the capacitance of the controller schematic hardware.
