The state of this latch may be used to clock timer
T5, or it may be output on a port pin (T6OUT).
The overflows / underflows of timer T6 can also be
used to clock the CAPCOM timers T0 or T1, and
to cause a reload from the CAPREL register.
The CAPREL register can capture the contents of
T5 from an external signal transition on the
corresponding port pin (CAPIN), and T5 may be
optionally cleared after the capture procedure.
This allows absolute time differences to be
measured or pulse multiplication to be performed
without software overhead.

The capture trigger (timer T5 to CAPREL) may
also be generated on transitions of GPT1 timer T3
inputs T3IN and / or T3EUD. This is useful when
T3 operates in Incremental Interface Mode.
Table 15 GPT2 timer input frequencies, resolution
and periods lists the timer input frequencies, reso-
lution and periods for each pre-scaler option at
25MHz CPU clock. This also applies to the Gated
Timer Mode of T6 and to the auxiliary timer T5 in
Timer and Gated Timer Mode.
