Provide port access per byte.

Declaration¶

Source position: portsh.inc line 46

var
  portb: type

  tport = object
  public
    property pp[w : Word]: Byte read readport write writeport; default;
  end;

Default instance of type TPort. Do not free. This variable is initialized in the unit initialization code, and freed at finalization.

Since there is a default property for a variable of this type, a sentence as

portb[221]:=12;

Will result in the byte 12 being written to port 221, if port is defined as a variable of type tport
