9.5.1.2 Controlling the timer unit
The timer unit is designed, so that events when combined with enabling flags start or stop
the counter. For example, setting bit TStartTxBegin = logic 1 enables control of received
data with the timer unit. In addition, the first received bit is indicated by the TxBegin event.
This combination starts the counter at the defined TReloadValue[7:0].
The timer stops automatically when the counter value is equal to zero or if a defined stop
event happens.
The main part of the timer unit is a down counter. As long as the down counter value is not
zero, it decrements its value with each timer clock cycle.
If the TAutoRestart flag is enabled, the timer does not decrement down to zero. On
reaching value 1, the timer reloads the next clock function with the TReloadValue[7:0].
The timer is started immediately by loading a value from the TimerReload register into the
counter module.
This is activated by one of the following events:
