Count Direction Control for Auxiliary Timer

The count direction of the auxiliary timer can be controlled in the same way as for the

core timer T6. The description and the table apply accordingly.

Timer T5 in Timer Mode or Gated Timer Mode

When the auxiliary timer T5 is programmed to timer mode or gated timer mode, its

operation is the same as described for the core timer T6. The descriptions, figures and

tables apply accordingly with one exception:

• There is no output toggle latch for T5.

Timer T5 in Counter Mode

Counter mode for the auxiliary timer T5 is selected by setting bit field T5M in register

T5CON to ‘001B’. In counter mode timer T5 can be clocked either by a transition at the

external input pin T5IN, or by a transition of timer T6’s output toggle latch T6OTL (i.e.

timer concatenation).
