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.

reaches the match value, the timer enable bit in TCR is cleared, and the interrupt
indicating that a match occurred is generated.
