7.2.2 Commands of the SSI in Extended Mode

OTP reset has to be performed. If not, the OTP is not read out and the OTP data is not available.

WRITE OTP: Writing of the OTP register. The written data is volatile. “Zero Angle” is the angle, which is set for zero position. “Wake enable”

enables the polling mode. “Sensitivity” is the gain setting in the signal path. “Redundancy is a number of bits, which allows the customer to

overwrite one of the customer OTP bits <0:11>.

PROG_OTP: Programming of the OTP register. Only Bits <0:15> can be programmed by the customer.

RD_OTP: Read out the content of the OTP register. Data written by WRITE_OTP and PROG_OTP is read out.

RD_OTP_ANA: Analog read out mode. The analog value of every OTP bit is available at pin 2 (PROG), which allows for a verification of the fuse

process. No data is available at the SSI.
