7.2 Serial 3-Wire R/W Connection
In this mode, the AS5134 is connected to the external controller via three signals: Chip Select (CS), Clock (DCLK) inputs and bi-directional DIO
(Data In/Out) output. The controller sends commands over the DIO pin at the beginning of each data transmission sequence, such as reading
the angle or putting the AS5134 in and out of the reduced power modes.
