9.4.2 Handling of Pins When Sub-Clock is Not Used

If the sub-clock is not in use, connect the XCIN pin to VSS via a resistor (to pull VSS down) and leave the XCOUT pin

open-circuit as shown in

Figure 9.9.

In addition, if an oscillator is not connected, set the sub-clock oscillator stop bit (SOSCCR.SOSTP) to 1 (stopping the

oscillator) and the sub-clock oscillator control bit in RTC control register 3 (RCR3.RTCEN) to 0 (stopping the sub-clock

oscillator). The value of some RTC registers related to the sub-clock will be undefined after a cold start. Accordingly, be

sure to set these bits after a cold start.
