Function
edge_sensitive_int_mb2
Description
0
Disable edge_sensitive_int detection interrupt for INT2
1
Enable edge_sensitive_int detection interrupt for INT2
In this section, all raw bits are classified as being triggered by either level-sensitive or edge-sensitive events, with the following
understanding of the terminology.
Level-sensitive events are events that are generally either high or low and which are not expected to change rapidly. The raw bit for level-
sensitive events is not latched and, therefore, always represents the true real-time status of the event in question.
Edge-sensitive events are events that only exist for an instant. The raw bits for edge-sensitive events are latched and, therefore, represent
the occurrence of an edge-sensitive event that happened in the past. Raw bits for edge-sensitive events must be cleared by the
corresponding clear bit.
