Overview
48.3 Overview
This section presents an overview of the TSI module. The following figure presents the
simplified TSI module block diagram.
48.3.1 Electrode capacitance measurement unit
The electrode capacitance measurement unit senses the capacitance of a TSI pin and
outputs a 16-bit result. This module is based in dual oscillator architecture. One oscillator
is connected to the external electrode array and oscillates according to the electrode
