The features of the eCAP
module include:
- Speed measurements of rotating machinery (for
example, toothed sprockets sensed by way of Hall
sensors)
- Elapsed time measurements between position
sensor pulses
- Period and duty cycle measurements of pulse
train signals
- Decoding current or voltage amplitude derived
from duty cycle encoded current/voltage sensors
The eCAP module features
described in this section include:
- 4-event time-stamp registers (each 32
bits)
- Edge polarity selection for up to four
sequenced time-stamp capture events
- Interrupt on either of the four events
- Single-shot capture of up to four event
time-stamps
- Continuous mode capture of time stamps in a
four-deep circular buffer
- Absolute time-stamp capture
- Difference (Delta) mode time-stamp capture
- When not used in capture mode, the eCAP module
can be configured as a single-channel PWM output
