1.
Accuracy depends on oscillator frequency accuracy.
2.
Tested at 25 °C in a restricted range and guaranteed by characterization.
3.
Rise and fall time depends on motor supply voltage value. Refer to SRout values in order to evaluate the actual rise and fall
time.
4.
Not valid for STBY/RST pin which has internal pull-down resistor.
5.
Not valid for SW and CS pins which have internal pull-up resistors.
6.
FLAG, BUSY and SYNC open drain outputs included.
7.
See Figure 18 – SPI timings diagram for details.
