Data Sheet
Figure 60
If T3M = ‘010
line stops the timer. If T3M = ‘011
the timer. In addition, the timer can be turned on or off by software using bit T3R. The
timer will only run, if T3R = ‘1’ and the gate is active. It will stop, if either T3R = ‘0’ or the
gate is inactive.
Note: A transition of the gate signal at line T3IN does not cause an interrupt request.
Timer 3 in Counter Mode
Counter mode for the core timer T3 is selected by setting bit field T3M in register T3CON
to ‘001
T3IN, which is an alternate function of P3.6. The event causing an increment or
decrement of the timer can be a positive, a negative, or both a positive and a negative
transition at this line. Bit field T3I in control register T3CON selects the triggering
transition (see Table 37 below).
