Input Capture (eCAP)<br />
Advanced capture can record up to four different events (useful for applicationssuch as<br />
remote control signal capture). Can also function as a PWM output<br />
To CAPx registers<br />

CAP1<br />
Dedicated <strong>32</strong>-<strong>bit</strong> Time Base<br />
• Uses prescaled CPU system clock.<br />
• Phase register allows synchronization with other counters<br />
• Event Qualifier can reset the counter on any of the four event loads<br />
Mode Select<br />
• Enables ECAPx pin as a input capture or PWM output<br />
Event Qualifier<br />
• Records event time stamps in absolute or delta modes<br />
Capture Control<br />
• Tells Event Qualifier which CAPx register to store data<br />
• Controls input capture in one-shot or continuous modes<br />
<strong>32</strong>-<strong>bit</strong> CAP1-4 Registers<br />
• Four independent registers, one for each event<br />
• In PWM mode, two can be used as shadow registers<br />
Interrupt and Flag Control<br />
• 7 different events can be configured to trigger an interrupt<br />
PWM Output<br />
• Timer-based PWM output option<br />
• Regular PWM with shadow loading<br />
