Caution:

When data is read, a wait time (tWAIT) of 1 μs is necessary within the rising edge of the

eighth clock that has set the command, and the falling edge of the first clock that has read

the data. This is required by the STFPC311 to process its internal commands/data (See

Figure 30)

Care must be taken to connect an external pull-up resistor to this pin (1 kΩ to 10 kΩ)

because the DOUT pin is an N-channel, open drain output pin (see Figure 31).
