7.0 SPECIAL FEATURES
7.1 Gestures
Single finger gestures are a fast and intuitive way to
navigate a feature rich human-machine interface. The
MTCH6301 supports 11 single finger gestures natively,
without requiring interaction from the master processor.
Tuning may be required depending on the layout of the
sensor, the time duration, and length of activation
required for your gesture supported application. The
most common defaults are already preloaded and
should serve most applications. These parameters and
their descriptions are available in the “Gestures” sec-
tion of the memory map (Section 6.0 “Memory Map”).
If your application requires ONLY gesture functionality,
and does not require touch coordinates, the touch
packet configuration byte (refer to Section 6.0 “Mem-
ory Map”) can be used to turn off all touch coordinate
data.

7.2 Sleep
Sleep functionality is enabled by default, and follows
the behavior detailed in Figure 7-2. This functionality
can be modified via the registers related to sleep.
SLP1: This delay controls how often the sensor is
scanned for a touch while in Sleep mode. Table 7-1
correlates the value of SLP1 to time (ms).
SLP2: Time (ms) without touch activity before controller
enters sleep mode.
Note: Gestures are NOT enabled by default,
and must be enabled via the gesture
packet configuration byte in RAM (refer to
Section 6.0 “Memory Map”).
