• The timer counts down
• When the count reaches 0000
• If a trigger occurs when counting, the timer reloads a new count and restarts counting
1/n
• An external trigger is input
• The timer overflows
• The one-shot start flag is set (= 1)
• A new count is reloaded after the count has reached 0000
• The count start flag is reset (= 0)
