Timer T5 Input Parameter Selection
Depends on the operating mode, see respective
sections for encoding:
Table 14-15 for Timer Mode and Gated Timer Mode
Table 14-11 for Counter Mode
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.
