MSP430FR5969: RTC clock source

Part Number: MSP430FR5969


Reading user guide of MSP430FR5969 it seems to me that the only RTC_B clock source is LF crystal; 

No possibility to source from ACLK or MCLK...

Does anyone know if am I right?

Thank you

    Hello pierangelo,

    The reason the RTC clock is sourced directly from the low-power 32Khz oscillator is when operating in LPM3.5, all clocks, including ACLK are disabled.  There is no provision to select a different clock source for the RTC.
