S32K RTC clock output

Hello,

I have a question about the RTC clock output:

In VLPS mode, is there RTC clock output if enabled in RTC module?

Thank you!

FF: Full functionality.In VLPR the system frequency is limited,but if a module does not have a function,it is still listed as FF.

Please refer to :S32K RM Table 39-4.Module operation in available power modes(continued)

It shows that RTC was FF in VLPS mode.So I think RTC_CLKOUT should work fine in VLPS.

Note: In VLPS mode,FIRC and SPLL clocks should be turned off, so they cannot be selected as RTC reference clocks.

BR!

Jim,
