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.
As can be seen from the port structure below, 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 dou-
ble-register mode. In these modes, unlike in com-
pare 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 out-
put 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 con-
nected to the internal bus. The port output latch
will receive the value from the internal bus and the
hardware triggered change will be lost.
As all other capture inputs, the capture input func-
tion of pins P2.15...P2.0 can also be used as
external interrupt inputs (200 ns sample rate at
40MHz 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 25ns at 40MHz CPU clock).
P2.15 in addition serves as input for CAPCOM2
timer T7 (T7IN).

tions of Port 2.
