| Bits | Field | Type | Default | Description |
|---|---|---|---|---|
| 7 | DOUBLE_DELAY | R/W | X | Start-up and shutdown delays from the ENx signals
0h = 0 ms to 15 ms with 1-ms steps 1h = 0 ms to 30 ms with 2-ms steps |
| 6 | CLKIN_PD | R/W | X | This bit selects the pulldown resistor on the CLKIN input pin.
0h = Pulldown resistor is disabled 1h = Pulldown resistor is enabled |
| 5 | Reserved | R/W | 0h | |
| 4 | EN3_PD | R/W | X | This bit selects the pulldown resistor on the EN3 (GPIO3) input pin.
0h = Pulldown resistor is disabled 1h = Pulldown resistor is enabled |
| 3 | TDIE_WARN_LEVEL | R/W | X | Thermal warning threshold level
0h = 125°C 1h = 137°C |
| 2 | EN2_PD | R/W | X | This bit selects the pulldown resistor on the EN2 (GPIO2) input pin.
0h = Pulldown resistor is disabled 1h = Pulldown resistor is enabled |
| 1 | EN1_PD | R/W | X | This bit selects the pulldown resistor on the EN1 (GPIO1) input pin.
0h = Pulldown resistor is disabled 1h = Pulldown resistor is enabled |
| 0 | Reserved | R/W | 0h |
