Datasheet - Detailed Descri p ti on

7.1.1 Commands of the SSI in Normal Mode

Note:

Gray bits can be ignored by the user.

GEN RST: A HI generates a reset of the AS5132. GEN RST must be set to LO after reset.

Hyst_Dis: Hysteresis disable.

PRE_COM_DYN <5:0>: Absolute dynamic pre-commutation value. Depending on the setup of the pole pairs, a mechanical angle offset can be

adjusted. The range is 0 to 63 mechanical degrees (LSBs).

MT-COUNTER <8:0>: The multiturn counter can be set or read over the interface.

EN PROG: This command with this data enables the access to the OTP register in extended mode. OTP Programming mode is only possible in

extended mode with special connection (see Figure 11).

EZ ERR: Indicates a wrong operation of the OTP memory after programming at room temperature.

ANGLE <8:0>: Absolute angle information with angular true resolution (360 steps).

LOCK ADC: Indicates a locked ADC. An angle value is only valid in case of a locked ADC. During sleep mode is the LOCK ADC bit LO.

AGC <5:1>: Automatic gain control value indicates the magnetic field strength.

P: Parity information of the 15 data bits. Odd parity.
