10 * Clock sources and parameters can be defined here in order of the clock tree and
11 * limitations of each MCU.
18 * MCU endianity. Define the constant as 1 for little endian.
20 #define __LITTLE_ENDIAN__ 0
22 * Clock configuration.
24 * The configuration of the clock sources consists of two steps.
25 * 1) Fill in all the multipliers, dividers and define all the sources.
26 * 2) Take the sources clocks values, apply the multipliers and dividers,
27 * calculate the resulting requency and fill in the RPP_something_FREQ.
28 * Those values are used in the code as a reference values and are not
29 * calculated automatically.
31 * Consult the datasheet to the MCU for more information about the clock tree
