DRO Mode

DRO data is supplied from I2C and is interpreted as 8-bit two’s complement signed number.

▪ For ACCELERATION_EN = 0:

• The most negative value corresponds to -100 % driving strength.

• The most positive value corresponds to +100 % driving strength.

• A zero value corresponds to no drive.

• The full range is between 127 (100 %) and -127 (-100 %), with -128 interpreted as -127 to keep the ranges

symmetrical

▪ For ACCELERATION_EN = 1:

• Negative values are omitted and substituted with zero.

• The most positive value corresponds to +100 % driving strength.

• Zero value corresponds to no drive.
