| Bits | Field | Type | Default | Description |
|---|---|---|---|---|
| 7 | EN_SPREAD_SPEC | R/W | X | This bit enables the spread-spectrum feature.
0h = Disabled 1h = Enabled |
| 6 | EN_PIN_CTRL_GPIO3 | R/W | X | This bit enables EN1 and EN2 pin control for GPIO3 (the GPIO3_SEL bit is set to 1h AND the GPIO3_DIR bit is set to 1h).
0h = Only GPIO3_OUT bit controls GPIO3 1h = GPIO3_OUT bit AND ENx pin control GPIO3 |
| 5 | EN_PIN_SELECT_GPIO3 | R/W | X | This bit enables EN1 and EN2 pin control for GPIO3.
0h = GPIO3_SEL bit AND EN1 pin control GPIO3 1h = GPIO3_SEL bit AND EN2 pin control GPIO3 |
| 4 | EN_PIN_CTRL_GPIO2 | R/W | X | This bit enables EN1 and EN3 pin control for GPIO2 (the GPIO2_SEL bit is set to 1h AND the GPIO2_DIR bit is set to 1h).
0h = Only GPIO2_OUT bit controls GPIO2 1h = GPIO2_OUT bit AND ENx pin control GPIO2 |
| 3 | EN_PIN_SELECT_GPIO2 | R/W | X | This bit enables EN1 and EN3 pin control for GPIO2
0h = GPIO2_SEL bit AND EN1 pin control GPIO2 1h = GPIO2_SEL bit AND EN3 pin control GPIO2 |
| 2 | GPIO3_SEL | R/W | X | This bit selects the EN3 pin function
0h = EN3 1h = GPIO3 |
| 1 | GPIO2_SEL | R/W | X | This bit selects the EN2 pin function
0h = EN2 1h = GPIO2 |
| 0 | GPIO1_SEL | R/W | X | This bit selects the EN1 pin function
0h = EN1 1h = GPIO1 |
