Datasheet - Detailed Description
7.2 Serial Synchronous Interface (SSI)
7.2.1   Commands of the SSI in Normal Mode
WD2COS / WD2SIN: xen_X disables Hall element X from the sensor array in the cosine or sine channel; xinv_X inverts the voltage output of Hall 
element X in the channels.
RD2COS / RD2SIN: The Hall array configuration for cosine and sine channel can be read out by these commands, initial values are 0.
SET TEST CFG 1: gen_rst HI triggers a digital reset.
WRITE CONFIG: go2sleep HI activates the low power mode of the AS5130. The power consumption is significantly reduced. go2sleep LO 
returns to normal operation mode. During low power mode, the lock bit in command 0 and command 1 is LO.
WRITE CUST: With wlsb_x the threshold level for generation of a WAKE pulse is set (only important in polling mode). The initial value is 4 LSB. 
No value lower than 4 LSB can be set. The maximum value is 127 LSB.
gain_x sets the gain in the signal
HYST_RST: setHyst enables an additional hysteresis of the digital output signal. It is enabled by default. Only after 2 consecutive equal signals 
the output is changed.
rst_otp forces the IC to read out the OTP in polling mode. This reset has to be performed after initial startup and every WAKE signal.
rst_multi resets the multi turn counter to 0.
READ CUST: With this command wlsb_x and gain_x can be read out.
RD_BOTH: Angle and multi turn counter value can be read out simultaneously by this command. Due to limited data size, the parity bit is not 
available in this command.
STORE REF: This command stores the actual angle as reference angle in the storage registers (only important in polling mode). The output is 
the stored angle (angle_stored), a flag, if the voltage at DVDD is OK (store_ok), a flag, if the supply voltage is OK (vdd_ok) and a check bit, if the
register was written.
RD_MULTI: Command for read out of multi turn register (multiturn) and AGC value (agc). Lock indicates a locked ADC and parity an even 
parity checksum.
RD_ANGLE: Command for read out of angle value and AGC value (agc). Lock indicates a locked ADC and parity an even parity checksum.
