General Purpose Timer Unit
x = 3
Figure 14-4 Block Diagram of Core Timer T3 in Gated Timer Mode
If T3M = ‘010
’, the timer is enabled when T3IN shows a low level. A high level at this
B
line stops the timer. If T3M = ‘011
’, line T3IN must have a high level in order to enable
B
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
’. In counter mode timer T3 is clocked by a transition at the external input pin
B
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 14-3 below).
