9.5.1.2 Controlling the timer unit
9.5.1 Timer unit implementation
Figure 8
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].
