47.6.3.7 Time-Stamp Capture

This feature is enabled when the Capture Time Stamp (STAMP) Event Action in Event Control register (EVCTRL.EVACT0(EVCTRL <2:0>)=0x6) is selected. The counter TOP value must be smaller than MAX.

When a capture event is detected, the COUNT value is copied into the corresponding Channel y Compare/Capture Value (CCy) register. In case of an overflow, the MAX value is copied into the corresponding CCy register.

When a valid captured value is present in the capture channel register, the corresponding Capture Channel y Interrupt Flag (INTFLAG.MCy) is set.

The timer/counter can detect capture overflow of the input capture channels: When a new capture event is detected while the Capture Channel interrupt flag (INTFLAG.MCy) is still set, the new time-stamp will not be stored and INTFLAG.ERR will be set.
