Data Sheet
Run control for auxiliary timers T2 and T4 can be handled by the associated Run Control
Bit T2R, T4R in register T2CON/T4CON. Alternatively, a remote control option (T2RC,
T4RC = ’1’) may be enabled to start and stop T2/T4 via the run bit T3R of core timer T3.
Timers T2 and T4 in Timer Mode or Gated Timer Mode
When the auxiliary timers T2 and T4 are programmed to timer mode or gated timer
mode, their operation is the same as described for the core timer T3. The descriptions,
figures and tables apply accordingly with two exceptions:
There is no TxOUT output line for T2 and T4.
There is no T4EUD input, and no T2IN input. Therefore Software must be programmed
accordingly.
Overflow/Underflow Monitoring is not supported (no output toggle latch).
Timer T4 in Counter Mode
In counter mode timer T4 can be clocked either by a transition at the respective external
input line T4IN, or by a transition of timer T3’s output toggle latch T3OTL.
Figure 66
The event causing an increment or decrement of the timer T4 can be a positive, a
negative, or both a positive and a negative transition at either the input line, or at the
output toggle latch T3OTL.
Bit field T4I in the respective control register T4CON selects the triggering transition (see
table below).
