5.4.3
Minimum Scan Period (i.e. PROXSCANPERIOD)
Similarly to touch operations (Cf. §4.6.5), if PROXSCANPERIOD is too short for proximity sensing operations to
be completed, the rate tick(s) affected are ignored until operations are completed and the following tick is taken
into account for the next planned operation.
Please note that compensation lasts about ~16 times longer than a normal proximity sensing operation.
