In Configuration Mode 01, the following general default settings apply:
The default voltages and the power-up sequence for all DC-DCs and LDOs in Configuration Mode 01
are shown below in Table 64 and Figure 66.
The time delay between each time slot is approximately 1.28ms.
Note that the Limit Switch is not enabled automatically in Configuration Mode 01; as a result, the
Limit Switch remains open when the WM8351 enters the ACTIVE state.
