In Configuration Mode 10, the following general default settings apply:
The default voltages and the power-up sequence for all DC-DCs and LDOs in Configuration Mode 10
are shown below in Table 66 and Figure 67.
The time delay between each time slot is approximately 1.28ms.
Note that the Limit Switch is not enabled automatically in Configuration Mode 10; as a result, the
Limit Switch remains open when the WM8350 enters the ACTIVE state.
