/ MSP430F20x3 Demo - Capacitive Touch Sensing 4-Key Demo
//
// Description: This demo implements a 4-key capacitive touch detection.
// The LED indicates the key which is pressed through four different levels of
// brightness. Key#1 -> 100%, Key#2 -> 75%, Key#3 -> 50%, Key#4 -> 25%.
// A calibration process is implemented to accommodate for possible variations
// in VLO frequency. Normal operating mode is LPM3.
//
// ACLK = VLO ~ 12kHz, MCLK = Calibrated 8MHz / 4 = 2MHz,
// SMCLK = Calibrated 8MHz
