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.
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

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

function of pins P2.15...P2.0 can also be used as
external interrupt inputs (250ns sample rate at
32MHz CPU clock).
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 31.25ns at 32MHz CPU clock).
