MSP430FR2153: About RTC, WDT and VLO at LPM4

Hi experts,

Can RTC and WDT be driven by using VLO as the source during LPM4?

My customer is considering the MSP430 for a low power consumption product. As far as we have tested, we have confirmed that the RTC and WDT work when the source of RTC and WDT is set to VLO during LPM4. As far as the UG is concerned, it does not appear to switch to LMP3 since VLO can be driven during LPM4.

However, from the datasheet "Table 6-1. Operating Modes", it is stated that WDT and VLO are turned off during LPM4, so we would like to confirm this.

Best regards,
O.H
