Capture
Action
Several capture actions can be selected by writing the Fault n Capture Action bits in the
Fault n Control register (FCTRLn.CAPTURE). When one of the capture operations is
selected, the counter value is captured when the fault occurs. These capture operations are
available:
• CAPT - the equivalent to a standard capture operation, for further details refer to
31.6.2.7 Capture Operations
• CAPTMIN - gets the minimum time stamped value: on each new local minimum
captured value, an event or interrupt is issued.
• CAPTMAX - gets the maximum time stamped value: on each new local maximum
captured value, an event or interrupt (IT) is issued, see Figure 31-28.
• LOCMIN - notifies by event or interrupt when a local minimum captured value is
detected.
• LOCMAX - notifies by event or interrupt when a local maximum captured value is
detected.
• DERIV0 - notifies by event or interrupt when a local extreme captured value is
detected, see Figure 31-29.
