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 (EPAx_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

WGR

Waveform Generator Reload; A/D Conversion

 

AD

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
