the output latch is clocked by the signal “Compare
Trigger”.
The direction of the pin should be set to output by
the user, otherwise the pin will be in the
high-impedance state and will not reflect the state
of the output latch.
Figure 26, the user software always has free
access to the port pin even when it is used as a
compare output. This is useful for setting up the
initial level of the pin when using compare mode 1
or the double-register mode. In these modes,
unlike in compare mode 3, the pin is not set to a
specific value when a compare match occurs, but
is toggled instead.
When the user wants to write to the port pin at the
same time a compare trigger tries to clock the
output latch, the write operation of the user
software has priority. Each time a CPU write
access to the port output latch occurs, the input

multiplexer of the port output latch is switched to
the line connected to the internal bus. The port
output latch will receive the value from the internal
bus and the hardware triggered change will be
lost.
function of pins P2.15...P2.0 can also be used as
external interrupt inputs (200ns sample rate at
40MHz CPU clock on PQFP144 devices and
250ns sample rate at 32MHz CPU clock on
TQFP144 devices).
The upper eight Port 2 lines (P2.15...P2.8) also
can serve as Fast External Interrupt inputs from
EX0IN to EX7IN (Fast external interrupt sampling
rate is 25ns at 40MHz CPU clock and 31.25ns at
32MHz CPU clock).
