Effective only if the Touch Screen Interleaved Mode is selected. Defines the Touch Screen Frequency compared to the
Trigger Frequency. 

If TSFREQ is 0 or 1, the Touch Screen Frequency is a sixth of the Trigger Frequency. 

Otherwise:

Touch Screen Frequency = Trigger Frequency / (2

TSFREQ+1

)

Programming 0 for TSSHTIM gives a Touch Screen Sample & Hold Time equal to 1/ADCCLK.

Touch Screen Sample & Hold Time = TSSHTIM/ADCCLK
