Touch module

This phone uses Synaptic capacitive touch series 3000.
The Synaptics MT touch module is interfaced to I2C bus of RAPU. RAPU’s GenIO123 is used for Touch INT.
The Synaptics MT touch module operates with VAUX1 supply output from EM ASIC.
Whenever the user touches the touch screen, the controller raises an interrupt to RAPU which initiates I2C

transactions to identify the locations the user touches on the display.
