Data Sheet - D e t a i l e d D e s c r i p t i o n
Table 10. Commands of the 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. “Sensitivity” is the
gain setting in the signal path. “Redundancy” is the number of bits, which allows the customer to overwrite one of the customer OTP bits <0:15>.
PROG_OTP: Programming of the OTP register. Only Bits <0:20> can be programmed by the customer. The internal factory settings are locked
by an “internal lock bit” and cannot be programmed.
READ_OTP: Read out the content of the OTP register. Data written by WRITE_OTP and PROG_OTP is read out.
READ ANA: Analog read out mode. The analog value of every OTP bit is available at pin 1 (PROG), which allows for a verification of the fuse
process. No data is available at the SSI.
tst: Test bits for internal testing (must be left unchanged).
ID (59:42): Chip identifier to track the device in the field
lock_otp (21): To disable the programming of the factory bits – write access is still possible
r_add (20:17): The following OTP bits can be modified according to the requirements of the application.
r_bit (16): Redundancy bit (functionality is only implemented in the user region)
Sensitivity (15:14): Trim bit for the gain of the amplifier after the demodulator
abi (13:12): Mode selection for the incremental signals
uvw (11:9): Number of poles of the brush less dc motor - impact to the uvw signals
zero angle (8:0): Trim bit for the zero angle information
LP: Enables the low power mode to reduce the current consumption - digital registers are not reset.
Notes:
7.12 Redundancy
For a better programming reliability, a redundancy is implemented. This function can be used in case if the programming of one bit fails. With an
address RA(4:0) one bit can be selected and programmed.

1. The Extended Mode can be enabled by sending command 16 (EN PROG).
2. The lock bit will be deleted during power down or sleep mode to ensure that the user is able to detect that the read out angle value is
3. In extended mode 1 data bit (wirte/read) requires 4 clock cycles
