GENERAL DESCRIPTION
1.4. CLOCK TREE
The STPC Elite integrates many features and
generates all its clocks from a single 14MHz
oscillator. This results in multiple clock domains as
described in
8/87
This is preliminary information on a new product now in development or undergoing evaluation. Details are subject to change without notice.

The speed of the PLLs is either fixed (DEVCLK),
either programmable by strap option (HCLK)

MCLK). When in synchronized mode, MCLK
speed is fixed to HCLKO speed and HCLKI is
generated from MCLKI.
