On Page 1, Under Features: Changed 3 mA shutdown current to 3 mA in scan stop mode current, changed
12 electrodes to 12 electrodes/capacitance sensing inputs in which 8 are multifunctional for LED driving and
GPIO, added two new bullets: Integrated independent autocalibration for each electrode input and
Autoconfiguration of charge current and charge time for each electrode input, Under Implementations: added
three bullets
Updated Table 1 Pin Descriptions, modified pin descriptions for Pins 4, 5, 7
In Section 3, added Power Supply paragraph, modified remaining paragraphs
In Table 2, changed ELEPROX to PROX_OOR, changed Register Names from: AFE Configuration and Filter
Configuration to: Filter/Global CDC Configuration and Filter/Global CDT Configuration, added new register for
