Data Sheet
Figure 73
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 signal T6OFL (toggle latch T6OTL).
Bit field T5P in control register T5CON selects the triggering transition (see table below).
Table 42
Note: Only state transitions of T6OTL which are caused by the overflows/underflows of
T5P

T6 will trigger the counter function of T5. Modifications of T6OTL via software will
NOT trigger the counter function of T5.
