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 SR
out
values in order to evaluate the actual rise and fall
time.
4. Not valid for the STBY/RST
pin which has an internal pull-down resistor.
5. Not valid for the SW and CS pins which have an internal pull-up resistor.
6. FLAG
, BUSY and SYNC open drain outputs included.
7. See Figure 20: SPI timings diagram on page 38 for details.
