Two on-chip analog comparators, one for BEMF
zero-crossing detection, the other for current
regulation or limitation
Seven selectable reference voltages for the
hysteresis comparator (0.2 V, 0.6 V, 1 V, 1.5 V,
2 V, 2.5 V, 3.5 V) and the possibility to select an
external reference pin (MCVREF).
8-bit timer (MTIM) with three compare registers
and two capture features, which may be used as
the Delay manager of a speed measurement
unit
Measurement window generator for BEMF
zero-crossing detection
Filter option for the zero-crossing detection.
Auto-calibrated prescaler with 16 division steps
8x8-bit multiplier
Phase input multiplexer
Sophisticated output management:
groups (high & low)

ously, for six-step motor drives

rect optocoupler drives.
