7.2 SPI Communication
The transmitted data consists of 14-bit data, an Error-Flag and a Parity bit. When writing data to the chip, the Error-Flag is not applicable. The
Parity is generated from the upper 15-bit and forms an even parity over the whole frame. The Error-Flag indicates that a failure occurred in a
previous transmission.
7.2.1 Command Package
Every command sent to the AS5050 is represented with the following layout.
