According to the comments in the official example code from Cirque, “Changes thresholds to improve detection of fingers.” This function was ported from Cirque’s example code and doesn’t have corresponding documentation. Thus, the defaults for this function’s parameters use the same values found in the official example. I’m unaware of any documented memory map for the Pinnacle ASIC as this function directly alters values in the Pinnacle ASIC’s memory. ALTER THESE PARAMETERS AT YOUR OWN RISK!
