5.2 Scope Commands
The host should always set the scope parameter when
initializing the part during normal operation as well as during
setup. Scope commands are persistent and apply to all
subsequent functions that are affected by scope, until a
different scope command is issued. On powerup or after reset
the device defaults to scope = 'all keys'.
Many functions only address one key regardless of the
current scope; in these cases the key being addressed is
always the key last set by the
‘
s
’
or
‘
x
’
and
‘
y
’
commands. If
the
‘
s
’
command was last set to key 9, then even though the
‘
S
’
command was issued afterwards the one-key scope will
remain key
‘
9
’
. Similarly if
‘
x
’
was set to 2 and
‘
y
’
to 3, then
the one-key scope will remain key x=2 / y=3 (key
#
14). This
rule operates for either Put or Get commands.

ention:
The numbering of keys goes by
row then column. For example, the key in row X=3, column
Y=1 (X3Y1) is key 7. The formula for conversion of an X-Y
location to a key number is
:
key number = X
_
row
+
(Y
_
column x 4)
Row and column numbers are per Fig. 1-5. Keys are acquired
in this same burst sequence, i.e. X0Y0, X1Y0, X2Y0 etc.

5.3 Status Commands
Status commands cause the sensor to report back
information related to keys and their signals.
It is not necessary to set the part to Get mode with these
commands, although it is advised to leave the part in Get
mode as a normal precaution (see Section 5.1)

Numeric '0'. Returns the signal level in 16-bit unsigned binary
for one key whose location is determined by scope. The least
significant byte is returned first.
Note that the signal direction is inverted
:
decreasing values
correspond to more touch due to the physics of key detection
described in Section 1.1.

truncated to zero. The return value is also limited to 255
(0xFF).
Increasing amounts of this value correspond to increasing
amounts of touch as the sign of signal is inverted (see 0x30

function is useful primarily for diagnostics and should
periodically be used to check for valid eeprom contents.
The checksum should be computed when the entire device's
settings, including the locked reference levels ('L' command)
are known. The host can then periodically test the checksum
to validate eeprom integrity. If needed, the eeprom can then
