When current limitation threshold is reached for the first time, a dedicated HBx_ILIM latch is set, indicating that
current limitation function has been activated. This latch is cleared on SPI readout.
The OFF time interval for current limitation (tOFF) is selectable via SPI according to HBx_toff bit:
