TMF8701 − Register Description
Figure 49:
DISTANCE_PEAK_1 Register
The sys clock registers is a running timer information – this value
is counting up (and wraps around to 0 again) as long as the
internal clock is running. As it is derived from the internal RC
oscillator and distance information is depending on its
accuracy, it can be used to correct an algorithm result by
comparing this clock with a more accurate clock inside the host.
For correctly updating of these registers by TMF8701, an I²C
blockread starting from address 0x1D until 0x27 shall be done.
