◆ RTC_SetWakeupTimer_10Minutes()

HAL_StatusTypeDef RTC_SetWakeupTimer_10Minutes ( void )

Configure RTC wakeup timer for 10 minutes.

Configure the RTC periodic wakeup timer.

Calculation for 10 minutes (600 seconds):

Using RTC_WAKEUPCLOCK_CK_SPRE_16BITS which provides a 1 Hz clock
This clock is derived from the RTC prescalers (ck_spre = 1 Hz)
Counter value for 10 minutes: 600 - 1 = 599
Maximum counter value is 0xFFFF (65535), which allows up to ~18.2 hours
So 10 minutes (600 seconds) is well within limits
