Detailed Description

This functional group provides status information on various aspects and properties of the Clock Manager state.

Typedef Documentation

◆ ALT_CLK_PLL_LOCK_STATUS_t

typedef enum ALT_CLK_PLL_LOCK_STATUS_e ALT_CLK_PLL_LOCK_STATUS_t

This type definition defines the lock condition status codes for each of the PLLs. If the PLL lock status condition is enabled (See: alt_clk_irq_enable()) then it contributes to the overall clkmgr_IRQ signal assertion state.

Enumeration Type Documentation

◆ ALT_CLK_PLL_LOCK_STATUS_e

enum ALT_CLK_PLL_LOCK_STATUS_e

This type definition defines the lock condition status codes for each of the PLLs. If the PLL lock status condition is enabled (See: alt_clk_irq_enable()) then it contributes to the overall clkmgr_IRQ signal assertion state.

Enumerator
ALT_MAIN_PLL_LOCK_ACHV	This condition is set if the Main PLL has achieved lock at least once since this condition was last cleared.
ALT_PERIPH_PLL_LOCK_ACHV	This condition is set if the Peripheral PLL has achieved lock at least once since this condition was last cleared.
ALT_SDR_PLL_LOCK_ACHV	This condition is set if the SDRAM PLL has achieved lock at least once since this condition was last cleared.
ALT_MAIN_PLL_LOCK_LOST	This condition is set if the Main PLL has lost lock at least once since this condition was last cleared.
ALT_PERIPH_PLL_LOCK_LOST	This condition is set if the Peripheral PLL has lost lock at least once since this condition was last cleared.
ALT_SDR_PLL_LOCK_LOST	This condition is set if the SDRAM PLL has lost lock at least once since this condition was last cleared.

Function Documentation

◆ alt_clk_lock_status_clear()

ALT_STATUS_CODE alt_clk_lock_status_clear ( ALT_CLK_PLL_LOCK_STATUS_t lock_stat_mask )

Clear the selected PLL lock status conditions.

This function clears assertions of one or more of the PLL lock status conditions.

NOTE: This function is used to clear clkmgr_IRQ interrupt signal source assertion conditions.

Parameters

lock_stat_mask Specifies the PLL lock status conditions to clear. lock_stat_mask is a mask of logically OR'ed ALT_CLK_PLL_LOCK_STATUS_t values designating the PLL lock conditions to clear.

Return values

ALT_E_SUCCESS	Successful status.
ALT_E_BAD_ARG	The lock_stat_mask argument contains an unknown condition value.

◆ alt_clk_lock_status_get()

uint32_t alt_clk_lock_status_get ( void )

Returns the PLL lock status condition values.

This function returns the value of the PLL lock status conditions.

Returns: The current values of the PLL lock status conditions as defined by the ALT_CLK_PLL_LOCK_STATUS_t mask bits. If the corresponding bit is set then the condition is asserted.

◆ alt_clk_pll_is_locked()

ALT_STATUS_CODE alt_clk_pll_is_locked ( ALT_CLK_t pll )

Returns ALT_E_TRUE if the designated PLL is currently locked and ALT_E_FALSE otherwise.
