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 (Table 5) in order to evaluate the actual
rise and fall time.
4.
Not valid for STBY/RST pins which have internal pull-down resistor.
5.
Not valid for SW and CS pins which have internal pull-up resistor.
6.
FLAG and SYNC open drain outputs included.
