Area
CORDIC_OUT(13:0): 14-bit absolute angular position data.
OCF (Offset Compensation Finished): logic high indicates the finished Offset Compensation Algorithm. As soon as this bit is set, the
AS5163 has completed the startup and the data is valid.
COF (Cordic Overflow): Logic high indicates an out of range error in the CORDIC part. When this bit is set, the CORDIC_OUT(13:0) data is
invalid. The absolute output maintains the last valid angular value. This alarm may be resolved by bringing the magnet within the X-Y-Z
tolerance limits.
AGC_VALUE (7:0): magnetic field indication.
DSP_RES resets the DSP part of the AS5163 the default value is 0. This is active low. The interface is not affected by this reset.
R1K_10K defines the threshold level for the OTP fuses. This bit can be changed for verification purpose. A verification of the programming
of the fuses is possible. The verification is mandatory after programming.

Write128 command: The trimming bits are written in the SFR memory.
Read128 command: The trimming bits are read back.
Upload command: The SFR memory is transferred into the OTP RAM.
Fuse command: The OTP RAM is written in the Poly Fuse cells.
Wait fuse time (6 ms)
Write command (R1K_10K=1): Poly Fuse cells are transferred into the RAM cells compared with 10KΩ resistor.
Download command: The OTP RAM is transferred into the SFR memory.
Read128 command: The fused bits are read back.
Write command (R1K_10K=0): Poly Fuse cells are transferred into the RAM cells compared with 1KΩ resistor.
Download command: The OTP RAM is transferred into the SFR memory.
Read128 command: The fused bits are read back.
Pass2Func command or POR: Go to Functional mode.
