| 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) 3: 1000 ms (minimum), 1200 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. |
