36.3.3 Terminal type
The current reading is continuously written to a shift register in the sensor. If
a data value needs to be read, the device will output a clock signal on the
clock line. With this clock signal, the device will then read the data from the
encoder's shift register. Absolute encoders provide their absolute data with
additional control information in the shift register if applicable.
