6.3.4 TO_ACTIVE

When a trigger causes the TO_ACTIVE sequence to execute, all rails power up in the recommended power up sequence as shown in Figure 6-5.

Figure 6-5 TO_ACTIVE Sequence

At the end of the TO_ACTIVE sequence the 'FORCE_EN_DRV_LOW' bit is cleared.

Note: After the TO_ACTIVE sequence the MCU is responsible for managing the EN_DRV.
