In Configuration Mode 11, the following general default settings apply:
The default voltages and the power-up sequence for all DC-DCs and LDOs in configuration mode 11
are shown below in Table 69 and Figure 68.
The time delay between each time slot is approximately 1.28ms.
Note that the Limit Switch is not enabled automatically in Configuration Mode 11; as a result, the
Limit Switch remains open when the WM8350 enters the ACTIVE state.

Note: In this Configuration Mode, LDO1 is enabled at all times. Therefore, the setting of
LDO1_ENSLOT has no effect.
