General Purpose Timer Unit
The General Purpose Timer Unit (GPT) represents very flexible multifunctional timer
structures which may be used for timing, event counting, pulse width measurement,
pulse generation, frequency multiplication, and other purposes.
In the C165H, there are following alternate function pins available: P3.3/T3OUT, P3.5/
T4IN/T3EUD/T2EUD, P3.6/T3IN and P3.7/T2IN, as shown in Figure 57.

- ^{Note: In the C165H, there are no external pins connected to Timer 5 and Timer 6.}
Additional, there is no second external connection to Timer 4 (T4EUD) and no
external connection to the register GPT2 CAPREL.
