Figure 5-7 : channel numbering for QTouch acquisition method when the SNS and SNSK
pins are connected to different ports.

When SNS and SNSK pins are available on different ports, the channel numbering
follows the pin numbering in the ports selected based on SNS_array and SNSK_array
bits enabled.The pins which needs to be used for touch should be provided in the Pin
Configurator Wizard in QTouch Studio and the pin configurator Wizard tool will generate
the SNS_array and SNSK_array masks and channel numbering will be based on which
pins are enabled for touch in consecutive way.Below is an example to illustrate the same:
