Byte 0:1 - MA1:0: Magnetic angle

Unsigned integer giving the magnetic angle in degree with the

configured resolution

Byte 2:5 - ILC3:0: Incremental linear

counter

Signed long giving the incremental linear counter in degree with the configured

resolution.

Byte 6 - KCONF: Configuration register

Unsigned char giving the configuration register

value.

Byte 8:7 - KRES: Resolution register

Contains the desired

resolution.

Byte 9 - CSSEND: Checksum - Senddata (Low-Byte of sum of

Byte[0..9])
