The following block diagram shows the timer module.
The timer unit is designed in a way, that several events in combination with enabling flags start or stop the
counter. For example, setting the bit TstartTxEnd to 1 enables to control the receiving of data using the timer
unit. In addition the first received bit is indicated by TxEndEvent. This combination starts the counter at the
defined TReloadValue.
The timer stops either automatically if the counter value is equal to zero, or if a defined stop event happens
(TautoRestart not enabled).
