Timers T2 and T4 in Counter Mode

Counter mode for the auxiliary timers T2 and T4 is selected by setting bit field TxM in the

respective register TxCON to ‘001B’. In counter mode timers T2 and T4 can be clocked

either by a transition at the respective external input pin TxIN, or by a transition of timer

T3’s output toggle latch T3OTL.

Figure 10-10 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 pin, or at the

toggle latch T3OTL.

Bit field TxI in the respective control register TxCON selects the triggering transition (see

Table 10-8).
