17.3.1.3 2-Dimensional Capacitive Voltage Divider Algorithm (2D CVD)

The 2-Dimensional CVD touch sensing algorithm uses CVDTXx output pins to form a matrix of sensors, as shown on Figure 17-6. CVDTXx active outputs are selected in ITCTXA, ITCTXB and ITCTXC registers. These selected CVDTXx pins are controlled by bits in Acquisition Sequencer commands.
