MOSC
Use the main oscillator as the source.
Note:
If the PIOSC is being used as the clock reference
for the PLL, the PIOSC is the clock source instead
of MOSC in Deep-Sleep mode.
0x1 PIOSC
Use the precision internal 16-MHz oscillator as the source.

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.
