Timer 6 in Counter Mode
Counter Mode for core Timer T6 is selected by setting bitfield T6M in register T6CON to
‘001
B
’. In Counter Mode, Timer T6 is clocked by a transition at the external input line
T6IN. 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. Bitfield T6I in control
register T6CON selects the triggering transition (see
Table 12-12
).
