I was looking at the K27 datasheet and noticed an error on the pinout page of the excel spreadsheet. If you open up the Pinout tab, it shows M5 twice (for NC and for RTC_WAKEUP_B). It looks like M3 should be RTC_WAKEUP_B and M5 should be NC. Can you confirm this is the case? I just want to make sure I don't mixup those two signals when creating my PCB layout.
Not sure where to post this so I thought I'd post it here. Thanks!
