Name
In the 80-pin version, PGUPD is internally tied to VDD, hence PG4 is pulled up.
In the 80-pin version, PHUPD is internally tied to VSS, hence PH4 is pulled down.

MCU ports can be configured for internal pull-up. To reduce power
consumption and RFI, the pin output drivers can be configured to
operate at a reduced drive level. Reduced drive causes a slight increase
in transition time depending on loading and should be used only for ports
which have a light loading.
