6.2.2.5 OSC1 Not Used
Figure 6-17 shows the recommended oscillator connections when OSC1 of the ZCE package is not used
and Figure 6-18 shows the recommended oscillator connections when OSC1 of the ZCZ package is not
used. An internal 10-kΩ pullup on the RTC_XTALIN terminal is turned on when OSC1 is disabled to
prevent this input from floating to an invalid logic level which may increase leakage current through the
oscillator input buffer. OSC1 is disabled by default after power is applied. Therefore, both RTC_XTALIN
and RTC_XTALOUT terminals should be a no connect (NC) when OSC1 is not used.
