Enhanced Capture (ECAP) modules provide accurate timing for different events. When
not being used for event capture, its resources can be used to generate a single
channel of asymmetrical PWM waveforms (configurable as either one capture input, or
as one auxiliary PWM output). Each ECAP module supports the following main features:
- 32-bit time base counter
- 4 x 32 bits event time-stamp
capture registers
- 4 stage sequencer (Mod4
counter), synchronized to external events
- Independent edge polarity
selection for up to four sequenced time-stamp capture events
- Input capture signal
pre-scaling (from 1 to 16)
- Interrupt capabilities on any
of the four capture events
- Support of different capture
modes (single shot capture, continuous mode capture, absolute timestamp
capture or delta mode time-stamp capture)
