When the count reaches 0000
If a trigger occurs when counting, the timer reloads a newcount and restarts counting
An external trigger is input
The timer overflows
The one-shot flag is set (=1)
A new count is reloaded after the count has reached 0000
The count start flag is reset (=0)
When counting has stopped and a value is written to Timer Ai, it is also written to the reload
When counting is in progress and a value is written to Timer Ai, it is written to only the reload
