Z value. With the Z value obtained from the register, the user simply needs to

multiply the Z value with the touchscreen panel resistance to obtain the touch

resistance.

The TSC_DATA register allows facilitation of another reading format with minimum

I2C transaction overhead by using the non autoincrement mode (or equivalent

mode in SPI). The data format is the same as TSC_DATA_XYZ, with the

exception that all the data fetched are from the same address.

Enable the EN bit of the TSC_CTRL register to start the touch detection and data

acquisition.

During the auto-hibernate mode, a touch detection can cause a wake-up to the

device only when the TSC is enabled and the touch detect status interrupt mask is

enabled.

In order to prevent confusion, it is recommended that the user not mix the data

fetching format (TSC_DATA_X, TSC_DATA_Y, TSC_DATA_Z, TSC_DATA_XYZ

and TSC_DATA) between one reading and the next.

It is also recommended that the user should perform a FIFO reset and TSC

disabling when the ADC or TSC setting are reconfigured.
