Reports the frequency of the Alternative High-Frequency Clock.

Function Usage

    /* BLE ECO configuration: ECO Frequency: 32 MHZ, Divider: 2 */
    /* Start-up time(uS): 1500, Load cap(pF): 9.9 */
    
    uint32_t startTime = (uint32_t)(1500 / 31.25);
    uint32_t loadCap   = (uint32_t)((9.9 - 7.5) / 0.075);
    
    /* Configure the BLE ECO clock */
    (void) Cy_BLE_EcoConfigure(CY_BLE_BLESS_ECO_FREQ_32MHZ, CY_BLE_SYS_ECO_CLK_DIV_2, loadCap, startTime, CY_BLE_ECO_VOLTAGE_REG_AUTO);
    
    /* In case if there is a need to get the BLE ECO frequency */
    uint32_t bleEcoFreq = Cy_SysClk_AltHfGetFrequency();
