Port 4 is a bidirectional I/O port with internal pull-up resistors.
Port 4 pins that have 1 written to them are pulled high by the
internal pull-up resistors and in that state can be used as inputs.
Secondary functions
P4.2: RD, Read line. This signal is same as the to output of the
pin RD available in some packages.
P4.3: WR, write line. This signal is same as the output of the pin
WR, which is only available in some package.
P4.7: VS, Vertical sync: ODD/Even, Odd/even field indicator.

A low level on this pin resets the device. An internal pull-up
resistor permits power-on reset using only one external
capacitor connected to V_SS.
