7:0 ZC[7:0]
Current Z value or speed capture MSB.
These bits contain the current captured BEMF value (ZN) in switched and
autoswitched mode or the MSB of the captured value of the [MTIM:MTIML] registers
in speed sensor mode. A read access to MZREG in this case disable the speed
captures up to MZPRV reading (refer to Speed measurement mode on page 227).

D value
These bits contain the compare value for simulated demagnetization (DN) and the
captured value for hardware demagnetization (DH) in switched and autoswitched
mode. In speed sensor mode, the register contains the value used for comparison
with MTIM registers to generate a speed error event.
