The EPA time (EPA x _TIME) registers are the event-time registers for the EPA channels. In capture
mode, the value of the reference timer is captured in EPA x _TIME when an input transition occurs.
Each event-time register is buffered, allowing the storage of two capture events at once. In compare
mode, the EPA triggers a compare event when the reference timer matches the value in EPA x _TIME.
EPA x _TIME is not buffered for compare mode.
