7.6 1-Wire PWM Connection
This configuration uses the least number of wires: only one line (PWM) is used for data, leaving the total number of connection to three, including
the supply lines. This type of configuration is especially useful for remote sensors. Ultra Low Power Mode is not possible in this configuration, as
there is no bi-directional data transmission. Pins that are not shown may be left open.

The PWM signal will be generated from the actual stored angle information. The zero-angle corrected value is buffered and fixed until the next
PWM-sequence is started. To ease the filtering of the PWM signal, a minimum pulse width is implemented in the protocol.
