5. Status Flags and Events
TMC4330A provides several status flags and status events to obtain short information on the
internal status or motor driver status. These flags and events can be read out from dedicated
registers. In the following chapter, you are informed about the generation of interrupts based
on status events. Status events can also be assigned to the first eight SPI status bits, which are
sent within each SPI datagram.
