6.1.7 Keyboard Scan Code Table
The keyboard contains three scan code sets. The system defaults to scan code Set 2,
but can be switched to Set 1 or Set 3. The following tables show the key numbers and
three scan code sets in hexadecimal values. All the keys are typematics except for the
pause key. When a key is pressed down, the make scan code is sent to the system.
When the key is released, its break code is sent. If two or more keys are held down,
only the last key pressed repeats at the typematic rate. Typematic operation stops
when the last pressed key is released, even if other keys are being released or some
other keys are still held down.
The following table shows three scan code sets used in the keyboard.
