RTC frequency trim. Value is a 10bit fixed point <4,6>
2's complement number. MSB Scaling = -8Hz.
The register indicates the error (in Hz) with respect to
the ideal 32768Hz) of the input crystal frequency.
Protected by security key.
Touch Panel Enable
0 = Disabled
1 = Enabled
Note - this bit is reset to 0 when the OFF power state is
entered.
Touch Panel Conversion Enable
0 = Disabled
1 = Enabled
In automatic mode, conversions are enabled by setting
this bit.
In manual mode (TCH_RATE = 0), setting this bit will
initiate a set of conversion; the bit is reset at the end of
the conversion.
