int pm_configure_clocks ( pm_freq_param_t * param )

Automatically configure the CPU, PBA, PBB, and HSB clocks according to the user wishes.

This function needs some parameters stored in a pm_freq_param_t structure:

cpu_f and pba_f are the wanted frequencies,
osc0_f is the oscillator 0 on-board frequency (e.g. FOSC0),
osc0_startup is the oscillator 0 startup time (e.g. OSC0_STARTUP).

The function will then configure the clocks using the following rules:

It first try to find a valid PLL frequency (the highest possible value to avoid jitter) in order to satisfy the CPU frequency,
It optimizes the configuration depending the various divide stages,
Then, the PBA frequency is configured from the CPU freq.
Note that HSB and PBB are configured with the same frequency as CPU.
Note also that the number of wait states of the flash read accesses is automatically set-up depending the CPU frequency. As a consequence, the application needs the FLASHC driver to compile.

The CPU, HSB and PBA frequencies programmed after configuration are stored back into cpu_f and pba_f.

Parameters

param pointer on the configuration structure.

Return values

PM_FREQ_STATUS_OK	Mode successfully initialized.
PM_FREQ_STATUS_FAIL	The configuration can not be done.
