PRODUCTION DATA
Figure 6-26 shows the digital comparator monitor events that can be configured as triggers.
The digital comparator has two options for asserting ALERT pin: event-based or window-based monitoring.
In event-based monitorin, the ALERT pin is asserted when an event is triggered based on the comparator configuration seen in Figure 6-27.
In window-based monitoring, the ALERT pin is only asserted when the number of event triggers recorded in CNT_MODE_x (0x1EA) crosses the threshold set in SPI register ALERT_THRESHOLD (0x1EC-0x1ED). Window-based monitoring is enabled in SPI register CNT_EN (0x1EA). Figure 6-28 shows an example of window-based monitoring.
