BIT FIELD TYPE DEFAULT DESCRIPTION

7-6 ZC_DET_TIME[1:0] R/W 0

This bit sets the minimum length of time devoted for detecting a zero crossing

(advanced use only).

0: 100 µs

1: 200 µs

2: 300 µs

3: 390 µs

5-4 AUTO_CAL_TIME[1:0] R/W 2

This bit sets the length of the auto calibration time. The AUTO_CAL_TIME[1:0]

bit should be enough time for the motor acceleration to settle when driven at the

RATED_VOLTAGE[7:0] value.

0: 150 ms (minimum), 350 ms (maximum)

1: 250 ms (minimum), 450 ms (maximum)

2: 500 ms (minimum), 700 ms (maximum)

0 OTP_PROGRAM R/W 0

This bit launches the programming process for one-time programmable (OTP)

memory which programs the contents of register 0x16 through 0x1A into

nonvolatile memory. This process can only be executed one time per device.

See the Programming On-Chip OTP Memory section for details.
