9-bit (+256/-255 turns).
Automatically updated during active mode at every 360º-/0º-
transition in each rotating direction.
The multiturn counter can be accessed over the serial interface
and is reset with a power-on-reset.
It will be frozen at the last valid state in low power mode.
Non-operational. Last status is frozen in Low power mode to
allow low power consumption and fast startup from low power
mode to operating mode.
Serial interface is active in low power mode to allow wakeup
over the serial interface.
PWM, incremental and BLDC outputs are invalid in low power
mode, they remain at their last valid state.
Current consumption in low power mode: typ. 30µA
