Data Sheet - D e t a i l e d D e s c r i p t i o n
Table 9. SSI in Extended Mode
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.
OTP Programming
For programming of the OTP, an additional voltage has to be applied to the pin PROG. It has to be buffered by a fast
100nF capacitor (ceramic) and a 10µF capacitor. The information to be programmed is set by command 25. The OTP
bits 16 to 45 are used for AMS factory trimming and cannot be overwritten.
