Data transfer starts with the falling edge of the CS signal. Data must appear at DI synchronized
to CLK and are accepted on the falling edge of the CLK signal. LSB (bit 0, SRR) has to be trans-
ferred 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.
