l There is no TxOUT output line for T2 and T4.
l Overflow/Underflow Monitoring is not supported (no output toggle latch).
Timers T2 and T4 in Counter Mode
In counter mode timers T2 and T4 can be clocked either by a transition at the respective
external input line TxIN, or by a transition of timer T3’s output toggle latch T3OTL.
Figure 14-10 Block Diagram of an Auxiliary Timer in Counter Mode
The event causing an increment or decrement of a timer can be a positive, a negative,
or both a positive and a negative transition at either the respective input line, or at the
output toggle latch T3OTL.
Bit field TxI in the respective control register TxCON selects the triggering transition (see
table below).
