Any attempt to write the CONFIG register when the motor is running causes the command
to be ignored and the NOTPERF_CMD flag to rise (see paragraph
STATUS
STATUS register
When HiZ flag is high it indicates that the bridges are in high impedance state. Whichever
motion command makes the device to exit from High Z state (HardStop and SoftStop
included), unless error flags forcing a High Z state are active.
The UVLO flag is active low and is set by an under-voltage lock out or reset events (power-
up included).
The TH_WRN, TH_SD, OCD flags are active low and indicate respectively thermal warning,
thermal shutdown and over-current detection events.
STEP_LOSS_A and STEP_LOSS_B flags are forced low when a stall is detected on bridge
A or bridge B respectively.
The NOTPERF_CMD and WRONG_CMD flags are active high and indicate respectively
that the command received by SPI can't be performed or does not exist at all.
The SW_F report the SW input status (low for open and high for closed).
The SW_EVN flag is active high and indicates a switch turn-on event (SW input falling
edge).
