10.5 TIMER OPERATION
10.5.1 Edge-aligned Up-counting Mode
The following figure shows a timer configured to reset the count (TC) and generate an interrupt on match in
Edge-aligned up-counting mode. The
end of the timer cycle where the match occurs, the timer count is reset. This gives a full length cycle to the match value.
The interrupt indicating that a match occurred is generated in the next clock after the timer reached the match value.
