Data transfer starts with the falling edge of the CS signal. Data must appear at DI syn-
chronized to CLK and are accepted on the falling edge of the CLK signal. LSB (bit 0,
SRR) has to be transferred first. Execution of new input data is enabled on the rising
edge of the CS signal. When CS is high, pin DO is in tri-state condition. This output is
enabled on the falling edge of CS. Output data will change their state with the rising
edge of CLK and stay stable until the next rising edge of CLK appears. LSB (bit 0, TP) is
transferred first.

Open load detection (low = on)
Overcurrent shutdown (high = overcurrent shutdown is active)
Software inhibit; low = standby, high = normal operation
(data transfer is not affected by standby function because the
digital part is still powered)
