32.768 kHz OSCI32 oscillator specifications
The 32.768 kHz OSCI32 oscillator is connected between RTC_XTI (oscillator amplifier
input) and RTC_XTO (oscillator amplifier output). It also requires two external capacitors of
18 pF(a), as shown on Figure 2.
OSCI32 is disabled by default and must be enabled by setting bit28-OSCI_EN of
PRCC_BACKUP_REG0 to have 32.768KHz oscillation when an XTAL pi-network is
connected to RTC_XTI/RTC_XTO pins.
The recommended oscillator specifications are shown in Table 27:
