Data Sheet - D e t a i l e d D e s c r i p t i o n
Table 9. Commands of the SSI in Normal Mode
SM_RES: State machine reset of the digital part of the device (soft reset).
EN PROG: Enables the access to the OTP register in Extended Mode.
WRITE CONFIG: LP HI activates the sleep mode of the AS5134. The power consumption is significantly reduced. LP LO returns to normal
operation mode. During sleep mode, the lock_adc bit in command 0 is LO.
RD_MT Counter: Command for read out of multi turn register.
otp_ok: Bit shows correct readout of the OTP register after startup. The bit is valid till the next OTP access.
RD_ANGLE: Command for read out of angle value and AGC value (agc). “Lock” indicates a locked ADC.
tst: Test bits for internal testing (must be left unchanged).
Hyst (11:10): Digital Hysteresis can be set via the digital interface 0,1,2 (default) 3 LSB
The hysteresis can be changed over the interface. An activation of the SM_RES bit is required. This can be performed in two steps -
SET MT COUNTER: Command for setting the Multi Turn Counter to a defined value.
LP: Default "0"; "1" for using the low power function.
lock_adc: Indicates that the tracking adc is in a locked status. For a valid angle (the magnetic field has to be in a certain range, which is
indicated by the agc value) or a missing magnet the lock_adc is set.

1. use WRITE CONFIG 1 command and write the selected hysteresis and SM_RES = ‘1’ into the device.
2. use again WRITE CONFIG 1 command and release SM_RES = ‘0’ with the same hysteresis setting.
