Power on state (serial communication)
The power-on reset state lasts from the rise of the power on pulse (1) created internally in the IC at power on to the second
chip select signal rising edge (3) that is input after (2). However, since there is actually a delay of a few hundred ns
internally in the IC the first data state starts at (4) and the IC enters the normal serial communication state after (4).
