If you use it as GPIO function, you don't need full-up resistor
If the RTC_WAKE_UP2 function is not uesd,
it can be connected to the GND

R1
470 kΩ
Remove when MCU control ‘RTC_PWR_KEY’.
This value should be chosen by customer application
to achieve the enough delay time depending on the
power-on time of VBAT.
For detail information, See 6.1

C1
1uF
Remove when MCU control ‘RTC_PWR_KEY’.
This value should be chosen by customer application
to achieve the enough delay time depending on the
power-on time of VBAT. Not to exceed 1uF.
For detail information, See 6.1
