the core timer T3. This configuration forms a 33-bit timer (16-bit core timer+T3OTL+16-
bit auxiliary timer).
The count directions of the two concatenated timers are not required to be the same.
This offers a wide variety of different configurations.
T3 can operate in timer, gated timer or counter mode in this case.

Auxiliary Timer in Reload Mode
Reload mode for the auxiliary timers T2 and T4 is selected by setting bit field TxM in the
respective register TxCON to ‘100
the contents of an auxiliary timer register, triggered by one of two different signals for
Timer T4 and by one signal (T3OFL/T3OTL) for Timer T2. The trigger signal is selected
the same way as the clock source for counter mode (see table above), i.e. a transition of
the auxiliary timer’s input or the output toggle latch T3OTL may trigger the reload.
Note: As opposed to Timer T4, for Timer T2 there is no input signal T2IN. Therefore, the
