Synchronization of T13 to T12
Timer T13 can be synchronized to a T12 event. Bitfields T13TEC and T13TED select the
event which is used to start Timer T13. The selected event sets bit T13R via HW, and
T13 starts counting. Combined with the Single-Shot mode, this feature can be used to
generate a programmable delay after a T12 event.
Figure 18-26 shows an example for the synchronization of T13 to a T12 event. Here, the
selected event is a compare-match (compare value = 2) while counting up. The clocks
of T12 and T13 can be different (other prescaler factor); the figure shows an example in
which T13 is clocked with half the frequency of T12.

Figure 18-26 Synchronization of T13 to T12
Bitfield T13TEC selects the trigger event to start T13 (automatic set of T13R for
synchronization to T12 compare signals) according to the combinations shown in
Table 18-6. Bitfield T13TED additionally specifies for which count direction of T12 the
selected trigger event should be regarded (see Table 18-7).
