Function Documentation

Cy_SysClk_ClkBakSetSource()

void Cy_SysClk_ClkBakSetSource

(

cy_en_clkbak_in_sources_t

source

)

Sets the source for the backup domain clock (clk_bak).

Parameters

source

cy_en_clkbak_in_sources_t

Note

clkLf is not available in all power modes. For this reason, WCO is the preferred source. If the WCO is routed through the clkLf multiplexer (see Cy_SysClk_ClkLfSetSource), select WCO directly - do not select clkLf.

Function Usage

    /* Scenario: Backup clock source needs to be updated to the WCO. */
 
    if(CY_SYSCLK_BAK_IN_WCO != Cy_SysClk_ClkBakGetSource())
    {
        Cy_SysClk_ClkBakSetSource(CY_SYSCLK_BAK_IN_WCO);
    }

Cy_SysClk_ClkBakGetSource()

cy_en_clkbak_in_sources_t Cy_SysClk_ClkBakGetSource

(

void

)

Reports the source for the backup domain clock (clk_bak).

Returns

cy_en_clkbak_in_sources_t

Function Usage

    /* Scenario: Backup clock source needs to be updated to the WCO. */
 
    if(CY_SYSCLK_BAK_IN_WCO != Cy_SysClk_ClkBakGetSource())
    {
        Cy_SysClk_ClkBakSetSource(CY_SYSCLK_BAK_IN_WCO);
    }
