Functions
void	cm_sys_clk_init (sys_clk_t type)
	Initialize clocks after power-up. More...
void	cm_sys_clk_set_priority (sys_clk_t *sys_clk_prio_array)
	Set the system clock priority. More...
cm_sys_clk_status_t	cm_sys_clk_request (sys_clk_t type)
	Request for system clock switch. More...
cm_sys_clk_status_t	cm_sys_clk_release (sys_clk_t type)
	Restores the system clock. It terminates a matching request. More...
void	cm_apb_set_clock_divider (apb_div_t div)
	Change the divider of the AMBA Peripheral Bus clock. More...
bool	cm_ahb_set_clock_divider (ahb_div_t div)
	Change the divider of the AMBA High speed Bus clock. More...
sys_clk_t	cm_sys_clk_get (void)
	Returns the sys_clk that the system uses at that moment. More...
sys_clk_t	cm_sys_clk_get_fromISR (void)
	Returns the sys_clk that the system uses at that moment (interrupt safe version). More...
apb_div_t	cm_apb_get_clock_divider (void)
	Returns the AMBA Peripheral Bus clock divider. More...
ahb_div_t	cm_ahb_get_clock_divider (void)
	Returns the AMBA High speed Bus clock divider. More...
cpu_clk_t	cm_cpu_clk_get (void)
	Returns the CPU clock frequency. More...
cpu_clk_t	cm_cpu_clk_get_fromISR (void)
	Returns the CPU clock frequency (interrupt safe). More...
void	cm_calibrate_rclp (void)
	Calibrate RCLP.
void	cm_calibrate_rc32m (void)
	Calibrate RC32M.
void	cm_wait_xtalm_ready (void)
	Block until the fast XTAL clock (XTALxxM) is ready. If the fast XTAL clock (XTALxxM) is running then the function exits immediately. More...
void	cm_wait_dblr_ready (void)
	Block until the Doubler is ready. More...
__RETAINED_CODE bool	cm_poll_xtalm_ready (void)
	Check if the fast XTAL clock (XTALxxM) is ready. More...
void	cm_enable_xtalm (void)
	Start the fast XTAL clock (XTALxxM) More...
__RETAINED_CODE void	cm_sys_clk_sleep (bool entering_sleep)
	Set the system clock (unprotected). More...
__RETAINED_CODE void	cm_halt_until_xtalm_ready (void)
	Halt until the fast XTAL clock (XTALxxM) has settled. More...
void	cm_register_xtal_ready_callback (void(*cb)(void))
	Register a callback function to be called then XTAL32M is ready. More...
__RETAINED_CODE void	cm_halt_until_sysclk_ready (void)
	Halt until system clock (either PLL or XTAL32M) is ready. More...
