10.4 EPA CHANNEL FUNCTIONAL OVERVIEW

The EPA has ten programmable capture/compare channels that can perform the following tasks.
•
capture the current timer value when a specified transition occurs on the EPA pin
•
start an A/D conversion when an event is captured or the timer value matches the
programmed value in the event-time register
•
clear, set, or toggle the EPA pin when the timer value matches the programmed value in the
event-time register
•
generate an interrupt when a capture or compare event occurs
•
generate an interrupt when a capture overrun occurs
•
reset its own base timer in compare mode
•
reset the opposite timer in both compare and capture mode
In addition to the capture/compare channels, the EPA also has two compare-only channels. They
support all the compare functions of the capture/compare channels.
