AMIS-30624_13 Datasheet, PDF (27/52 Pages) ON Semiconductor – I2C Micro-stepping Motor Driver

AMIS−30624, NCV70624
Note: The Secure Position is coded on 11 bits only,
providing actually the most significant bits of the position, the
non coded least significant bits being set to ‘0’. The Secure
Position in OTP has only 9 bits. The two least significant bits
are loaded as ‘0’ to RAM when copied from OTP.
