• TSMODE: Touchscreen Mode
When TSMOD equals 01 or 10 (i.e. 4-wire mode), channel 0, 1, 2 and 3 must not be used for classic ADC conversions.
When TSMOD equals 11 (i.e. 5-wire mode), channel 0, 1, 2, 3, and 4 must not be used.
• TSAV: Touchscreen Average
• TSFREQ: Touchscreen Frequency
Defines the Touchscreen Frequency compared to the Trigger Frequency.
TSFREQ must be greater or equal to TSAV.
The Touchscreen Frequency is:
11053B–ATARM–22-Sep-11
