Symbol defined if an ATxmega
Device is used for QMatrix
sensing technology
Range of values
Define this symbol to indicate QMatrix
acquisition method is required
Value should be same as the number of
channels that the library supports
Value should be same as the number of X
lines that the library supports. Refer to
library selection guide
Value should be same as the number of Y
lines that the library supports. Refer to
library selection guide
Needs to be added in case user needs to
configure ROTOR/SLIDER
Needs to be removed for ALL KEYS
configuration
Subject to support for rotors/sliders in the
library selected.
Please refer to section 5.6.8
Maximum number of ports that the X lines
can spread is 3.
Note: Code memory required increases
with the increase in NUM_X_PORTS
