Data Content:
Data only for read:
CORDIC_OUT(13:0) : 14-bit absolute angular position data.
OCF ( O ffset C ompensation F inished): 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 ( C ordic O ver f low): 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.
Data for write and read:
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.
8.2.2
Programming Procedure
Note: After programming the OTP fuses, a verification is mandatory. The procedure described below must be strictly followed to ensure
properly programmed OTP fuses.
Pull-up / Pull-down on OUT pin
VDD=5V
Wait startup time, device enters communication mode
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 10K Ω 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 1K Ω 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.
