MnMXS1~MnMXS0: Multiplexer Key Select
MnDFEN: Multi-frequency control
0: Disable
1: Enable
MnFILEN: Filter function control
0: Disable
1: Enable
MnSOFC: C to F OSC frequency hopping function control
0: The frequency hopping function is controlled by MnSOF2~ MnSOF0 bits
1: The frequency hopping function is controlled by hardware regardless of what is
the state of MnSOF2~ MnSOF0 bits
MnSOF2~ MnSOF0: Selecting key OSC and ref OSC frequency as C to F OSC is
controlled by software
000: 1380kHz
001: 1500kHz
010: 1670kHz
011: 1830kHz
100: 2000kHz
101: 2230kHz
110: 2460kHz
111: 2740kHz
The frequency which is mentioned here willl be changed when the external or internal
capacitor is with different value. if the touch key operates at a frequency of 2MHz,
users can adjust the frequency in scale when select other frequency.
