here is the problem description for the Valve driver (DRV8873S-Q1) from TI:
We need to configure the valve driver to independent half bridge mode:
(IC1 Control Register 0x52).
However, the behaviour of the driver blocks always appears as if the "Default Mode" (PWM) is still active. We already read-out the control register and the right value for independent mode is written on the register but it still works as PWM mode.
