By default, the TSC ID is set to 0x68, and the TSC is operating from its internal 2.5V
Regulator (LDO) and internal oscillator.
The (optional) tuning capacitor C14 is not mounted by default. In case of touch applications
with very high offset capacitance, a small (some few pF) can be mounted here to
compensate the offset capacitance of the touch input pins. Please refer to the 'basic tuning
process' chapter later in this document for details about the tuning capacitor.
Please refer to the TSC documentation (on CD) for details about TSC operation and
configuration.
3.7 TSC User LEDs (JP: 11, 12, 13, 14)
Four LEDs are connected to the TSC's GPIO pins. The TSC can control the LEDs by
switching or PWM dimming.
