Description
Clock Source
Specifies the clock source during Deep-Sleep mode.
Value Description
0x0 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.
0x2 Reserved
0x3 30 kHz
Use the 30-kHz internal oscillator as the source.
0x4-0x7 Reserved
0x0
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.
