The EPA control (EPA x _CON) registers control the functions of their assigned capture/compare
channels.

Re-enable
Re-enable applies to the compare mode only. It allows a compare event
to continue to execute each time the event-time register (EPA x _TIME)
matches the reference timer rather than only upon the first time match.
0 = compare function is disabled after a single event
1 = compare function always enabled
Waveform Generator Reload; A/D Conversion
The function of this bit depends on the EPA channel.
For EPA capture/compare channels 0, 2, 4:
The WGR bit allows you to use the EPA activities to cause the reload
of new values in the waveform generator.
0 = no action
1 = enables waveform generator reload
For EPA capture/compare channels 1, 3, 5:
The AD bit allows you to use the EPA activities to start an A/D
conversion that has been previously set up in the A/D control
registers.
0 = causes no A/D action
1 = starts an A/D conversion on an output compare
Reset Opposite Timer
Controls different functions for capture and compare modes.
In Capture Mode:
0 = causes no action
1 = resets the opposite timer
In Compare Mode:
Selects the timer that is to be reset if the RT bit is set.
0 = selects the reference timer for possible reset
1 = selects the opposite timer for possible reset
The TB bit (bit 7) selects which is the reference timer and which is the
opposite timer.
