Provide port access per byte.
Source position: portsh.inc line 65
var portb: tport; |
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
