PRODUCTION DATA
The ENABLEn pin is used to control the outputs of the device. When ENABLEn is low, the output H-bridges are enabled. When ENABLEn is high, the H-bridges are disabled and the outputs are in a high-impedance state.
Note that when ENABLEn is high, the input pins and control logic, including the indexer (STEP and DIR pins) are still functional.
| SLEEPn | ENABLEn | H-BRIDGE |

| 0 | X | Disabled |
| 1 | 1 | Disabled |
