Timer T5 Run Control
The auxiliary timer T5 can be started or stopped by software in two different ways:
•
Through the associated timer run bit (T5R). In this case it is required that the
respective control bit T5RC = 0.
•
Through the core timer’s run bit (T6R). In this case the respective remote control bit
must be set (T5RC = 1).
The selected run bit is relevant in all operating modes of T5. Setting the bit will start the
timer, clearing the bit stops the timer.
