32kHz oscillator
OSC32K_ENA = 1
32kHz Oscillator is enabled
Real Time Clock
RTC_TICK_ENA = 1
RTC_CLKSRC = 0
Real Time Clock is enabled
LDO1
LDO1_PIN_MODE = 1

Crystal detect
mode
Crystal detect mode is not enabled.
The default voltages and the power-up sequence for all DC-DCs and LDOs in Configuration Mode 01
are shown below in Table 65 and Figure 66.
