21. The PD pin must be asserted at power up to ensure proper crystal startup.
22. When X13OUT is enabled.
23. Both the polarity and the drive method of the IRQ pin are programmable. See page 11 for more details. Figure 12-6 illustrates default values for the Configuration
24. A wakeup event is triggered when the PD pin is deasserted. Figure 12-6 illustrates a wakeup event configured to trigger an IRQ pin event via the Wake Enable
