I am using RTC_LDD component for my board with KL25Z. In component settings I have selected, ERCLK32K as clock source. As I don't have any oscillator to connect to my RTC_CLKIN, In CPU settings I have selected system oscillator 0(I have read in user manual that I can source ERCLK32K from system oscillator) as ERCLK32K source. But I am getting an error that "system oscillator is not in low frequency range"
