1.8. CLOCK TREE
The STPC Atlas integrates many features and
generates all its clocks from a single 14MHz
oscillator. This results in multiple clock domains as
described in

The speed of the PLLs is either fixed (DEVCLK),
either programmable by strap option (HCLK)
either programmable by software (DCLK, MCLK).
When in synchronized mode, MCLK speed is fixed
to HCLKO speed and HCLKI is generated from
MCLKI.
