from sourcing current into the external device that is
driving the input pin.
It is not allowed to drive Port 3.6 to logic low level while
reset state changes from the active to inactive state
otherwise a special test mode is activated.

Port pin
Secondary functions can be selected individually and
independently for the pins of Port 1 and 3. Further
information on Port 1's secondary functions is given in
Section 2.9. on page
control signals automatically as long as the pin corre-
sponding to the appropriate signal is programmed as
an input, i. e. if the corresponding bit latch in the P3
special function register contains a ‘one’.
