Connect Rr, Cr, Rc, and Cc to each touch electrode, as shown in the above figure.
Refer to the design tool (B6TWWorkbench) for their actual values.
Connect a bypass capacitor of about 0.1 µF between Vdd and Vss using as short wires as possible.

Output pin to indicate operation.
[Normal measurement mode] outputs measured results.
[Setup mode] When the setup mode is entered, CHG pin changes to high. However,
Output pin for measured result
[On/off output mode] channel 1 output (active low)
[Serial communication mode] serial communication chip select input
[On/off output mode] channel 0 output (active low)
[Serial communication mode] output of measurement finish.
Two output modes are available in serial communication mode:
when an EEPROM write command is received and data is being written into
EEPROM, this pin is low.

2.
High-signal outputs every time a measurement finishes.
High-signal outputs when the condition changes in any one of the
channels (touch→no touch, no touch→touch).
