: Slelecting 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
2
MHz,
