Port D Considerations
Example 1: Configuring Port D as OUTPUT PORT or FLAG OUTPUT - The case where the configuration
by the shared pins is the same as the initial data from the OUTPUT PORT configured
The figure below shows the case where the initial data from the OUTPUT PORT does not conflict with the
configuration by shared pins even if port D is configured as the OUTPUT PORT or FLAG OUTPUT. Port D
remains in high-impedance state while the reset signal (nRESET) remains low. OUTPUT PORT remains in
high-impedance state during the period from the falling edge of reset to the beginning of the first output
data received. During these high-impedance periods, each input to port D is defined by the external pull-up
(High) or pull-down (Low) resister. When port D is configured as FLAG OUTPUT, it starts driving right after
the deassertion of the reset signal.
