The oscillator amplifier specifications are shown in the following table:
Figure 3. 32.768 kHz crystal connection
To drive the 32.768 kHz crystal pins from an external clock source:
Disable the oscillator (bit28-OSCI_EN = 0b in PRCC_BACKUP_REG0 register). This
disables the internal inverter, thus reducing the power consumption to minimum. This
also allows to drive RTC_XTI input even when a crystal is connected between
RTC_XTI and RTC_XTO pins.
Drive the RTC_XTI pin with a square signal or a sine wave.
