Ctrl-T. In Put mode, sets the MSB of equation constant C1
for boundary checking purposes. The part must be in Put
mode for this command to work.
Ctrl-W. In Put mode, sets whether the noise sync feature is
enabled or disabled. The part must be in Put mode for this
command to work.
The function has global scope. The default value is 5, which
corresponds to the reference circuit on page 10. A change in
this parameter only has effect after a reset or recalibration of
all keys.
The settings are:
0: off {factory default}
1: on
This function has global scope. The default value is 0 (off).
Valid values are from 0 to 127 decimal. Each count of the
MSB has a value 256x that of the LSB.
This feature can be used to synchronize the part to an
external repetitive source of e-field which might interfere with
the sensor signals, for example 50 or 60Hz fields from
adjacent power wiring. By doing so the part becomes immune
to the noise source.
In Get mode this function returns the current ^T value.
Refer to ^U (0x15) for the LSB definition.

Ctrl-U. In Put mode, sets the LSB of equation constant C1 for
boundary checking purposes. The part must be in Put mode
for this command to work.
The function has global scope. The default value is 0xE9,
which corresponds to the reference circuit on page 10. A
change in this parameter only has effect after a reset or
recalibration of all keys.
Valid values are from 0 to 255 decimal. The value of the LSB
must be combined with the value of the MSB to form the total
value.
In Get mode this function returns the current ^U value.
Refer to ^T (0x14) for the MSB definition.

Ctrl-V. In Put mode, sets equation constant C2 for boundary

command to work.
This function has global scope. The default value is 8, which
corresponds to the reference circuit on page 10. A change in
this parameter only has effect after a reset or recalibration of
all keys.
Valid values are from 0 to 255 decimal.
In Get mode this function returns the current ^V value.
