Register 10: Deep Sleep Clock Configuration (DSLPCLKCFG), offset 0x144
This register is used to automatically switch from the main oscillator to the internal oscillator when
entering Deep-Sleep mode. The system clock source is the main oscillator by default. When this
register is set, the internal oscillator is powered up and the main oscillator is powered down. When
the Deep-Sleep exit event occurs, hardware brings the system clock back to the source and frequency
it had at the onset of Deep-Sleep mode.

Description
Software should not rely on the value of a reserved bit. To provide
compatibility with future products, the value of a reserved bit should be
preserved across a read-modify-write operation.

When set, forces IOSC to be clock source during Deep-Sleep (overrides
DSOSCSRC field if set)
