DCO Maximum Frequency with 32.768 kHz Reference
The DMX32 bit controls whether or not the DCO frequency range is narrowed to its maximum frequency
with a 32.768 kHz reference.
The following table identifies settings for the DCO frequency range.
NOTE: The system clocks derived from this source should not exceed their specified maximums.

DCO Range Select
The DRS bits select the frequency range for the FLL output, DCOOUT. When the LP bit is set, writes to
the DRS bits are ignored. The DRST read field indicates the current frequency range for DCOOUT. The
DRST field does not update immediately after a write to the DRS field due to internal synchronization
between clock domains. Refer to DCO Frequency Range table for more details.

DCO has a default range of 25%.
DCO is fine-tuned for maximum frequency with 32.768 kHz reference.
Encoding 0 — Low range (reset default).
Encoding 1 — Mid range.
