Classical non-SPI control mode (stand alone mode)
The driver can be controlled by analog current control signals and digital phase signals. To enable this
mode, tie pin SPE to GND. In this mode, the SPI interface is disabled and the SPI input pins have
alternate functions. The internal DACs are forced to “1111”.

Tie to GND to enable stand alone mode
Enable mixed decay for bridge A (low = enable)
Enable mixed decay for bridge B (low = enable)
Polarity bridge A (low = current flow from output OA1 to OA2)
Polarity bridge B (low = current flow from output OB1 to OB2)
Error output (high = overcurrent on any bridge, or overtemperature). In this
mode, the pin is never tristated.
Standby mode (high active), high causes a low power mode of the device.
Setting this pin high also resets all error conditions.
Current control for bridge A, resp. bridge B. Refer to AGND. The sense
resistor trip voltage is 0.34V when the input voltage is 2.0V. Maximum input
voltage is 3.0V.

are inverted when compared to stand alone mode.
