11.0. MENU Keypad
There is a group of push buttons on the Easy8051 v6 development system which constitute a navigation keypad called MENU. The
main feature of the MENU keypad is the arrangement of its push buttons marked as left, right, up and down arrows. Besides, there are
also two additional push buttons referred to by ENTER and CANCEL. MENU push buttons are connected in the same way as the port
PORT3 push buttons. Their function is determined by the user when writing the program for the microcontroller.
