# Hardware Limit Mode

The Limit mode of operation is controlled by the LIMIT bit in the TUxyCON1 register. Setting the LIMIT bit will cause the counter/timer value to not advance when the TUxyTMR counter register value equals the value in the TUxyPR period register (even though the timer is still “running”). If the LIMIT bit is cleared, the counter/timer will continue to count through the PR match and roll over at the maximum value of the TUxyTMR counter register. The LIMIT bit is not synchronized to the counter/timer clock and does not need to be changed when the ON bit is set.
Important:
1. 1.This bit is relevant when RESET = ‘b00 (No hardware Reset) and counter equals PR.
2. 2. The effect of Limit mode is to prevent the counter from exceeding PR value. Reset and CLR events are not prevented from clearing the counter.
