AS5046 Programmable 360° Magnetic Angle Encoder – Preliminary Data Sheet
8
The AS5046 is accessible via an bi-directional serial interface.
CSn must be low during serial data transmission.
8.1
The registers in the AS5046 are available in a data length of 8 bit (1 byte), 24 bit (3 bytes) and 32 bit (4 bytes).
Shown below in Figure 6 is a common 8-bit data transfer.
Figure 7 shows a transfer timing diagram for the first 16 bits of the Serial Interface Unit.
